  • Problem installing Ubuntu 13.10 alongside Windows 8

    - by kustrle
    What I have: Sony Vaio laptop (SVE1512E6EW) with preinstalled Windows 8. I disabled Secure Boot some time ago in BIOS. I already had Ubuntu (previous version) installed on it, but removed it some time ago. After that, the default Windows boot menu is showing up everytime I boot up computer, and the only entry is Windows 8. What I did: Burned Ubuntu 13.10 DVD Restarted computer and booted from it Chosen Install Ubuntu (not Try Ubuntu) Created new ext4 partition from free space Installed Ubuntu on it What happened: After the installation I restarted computer. Windows default boot menu showed up (just as before) and the only entry was still Windows 8. If you have any additional questions I will try to answer them as fast as possible.

  • Ubuntu launch option on startup remains

    - by rQw
    I used windows installer to install Ubuntu and it was getting errors on bootup. Well that didn't work, I guess I'll try and boot from a USB to install it. However, after messing around with uninstalling (aka deleting Ubuntu folder after booting into Win7) I cannot get rid of the launch option. There is nothing in Computer Management because I never actually booted into Ubuntu to create space on my HDD for the OS. I can't just uninstall using Program and Features in Control Panel (because I already deleted the folder) Now everytime I boot up it gives me the options of booting into Windows 7 or Ubuntu, how do I disable this page/get rid of the Ubuntu launch option?

  • Ubuntu can't shut down correctly [closed]

    - by Luc1Hz
    Possible Duplicate: Problem with ubuntu 12.04 I am new to Ubuntu. I've installed 12.04 version of Ubuntu. It works fine but sometimes when i shutdown my PC from Ubuntu and when I try to start it again,nothing shows on the screen. It's always black screen instead of Acer logo (I have Acer aspire 5573) and the system restart again and again but and doesn't allow me to choose a OS (Ubuntu/windows,i use dualboot) To fix this I have to remove the battery and put it again.Then everything works fine. How do i fix this issue? I think that could be a incompatibility with the PC because everything works fine with windows. Thanks!

  • Can I install 12.10 on Ainol Novo7 Venus?

    - by Jens Grünwald
    Is it possible to install Ubuntu on my Ainol Novo7 Venus? I don't want any tablet-version of ubuntu, because I like ubuntu how it is and think there is no need for a tablet-version (I know there is no tablet-version, but many questions after it). So I want to install full desktop-ubuntu 12.10 with unity and everything, but I want a dual-boot with my existing android installation. Is that possible? If so, how? Is 16gb enough for ubuntu or should I buy an extra sd-card for it?

  • Android - How do I load a contact Photo?

    - by PaulH
    I'm having trouble loading a photo for a contact in Android. I've googled for an answer, but so far have come up empty. Does anyone have an example of querying for a Contact, then loading the Photo? So, given a contactUri which comes from an Activity result called using startActivityForResult(new Intent(Intent.ACTION_PICK,ContactsContract.CommonDataKinds.Phone.CONTENT_URI),PICK_CONTACT_REQUEST) is: content://com.android.contacts/data/1557 The loadContact(..) works fine. However when I call the getPhoto(...) method, I get a null value for the photo InputStream. It is also confusing because the URI values are different. The contactPhotoUri evaluates to: content://com.android.contacts/contacts/1557 See the comments inline in the code below. class ContactAccessor { /** * Retrieves the contact information. */ public ContactInfo loadContact(ContentResolver contentResolver, Uri contactUri) { //contactUri --> content://com.android.contacts/data/1557 ContactInfo contactInfo = new ContactInfo(); // Load the display name for the specified person Cursor cursor = contentResolver.query(contactUri, new String[]{Contacts._ID, Contacts.DISPLAY_NAME, Phone.NUMBER, Contacts.PHOTO_ID}, null, null, null); try { if (cursor.moveToFirst()) { contactInfo.setId(cursor.getLong(0)); contactInfo.setDisplayName(cursor.getString(1)); contactInfo.setPhoneNumber(cursor.getString(2)); } } finally { cursor.close(); } return contactInfo; // <-- returns info for contact } public Bitmap getPhoto(ContentResolver contentResolver, Long contactId) { Uri contactPhotoUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, contactId); // contactPhotoUri --> content://com.android.contacts/contacts/1557 InputStream photoDataStream = Contacts.openContactPhotoInputStream(contentResolver,contactPhotoUri); // <-- always null Bitmap photo = BitmapFactory.decodeStream(photoDataStream); return photo; } public class ContactInfo { private long id; private String displayName; private String phoneNumber; private Uri photoUri; public void setDisplayName(String displayName) { this.displayName = displayName; } public String getDisplayName() { return displayName; } public void setPhoneNumber(String phoneNumber) { this.phoneNumber = phoneNumber; } public String getPhoneNumber() { return phoneNumber; } public Uri getPhotoUri() { return this.photoUri; } public void setPhotoUri(Uri photoUri) { this.photoUri = photoUri; } public long getId() { return this.id; } public void setId(long id) { this.id = id; } } } Clearly, I'm doing something wrong here, but I can't seem to figure out what the problem is. Thanks.

  • How to attach a scroll bar to a canvas in android ?

    - by panzerschreck
    Hello, I am drawing up a grid on a canvas as below, I have not been able to get the scroll bar to appear, I looked around for examples, but none of them give details on drawing scroll bars for custom views. Your help is much appreciated. public class GridActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // i tried to do as in the documentation nothing seems to happen LinearLayout lLayout = new LinearLayout(this); lLayout.addView(new CustomDrawableView(this), new ViewGroup.LayoutParams(800,600)); FrameLayout fLayout = new FrameLayout(this); fLayout.addView(lLayout, new ViewGroup.LayoutParams(800,600)); setContentView(fLayout); } private class GridView extends ScrollView { private ShapeDrawable[] mDrawable; public GridView (Context context) { // some initialization } protected void onDraw(Canvas canvas) { for each i mDrawable[i].draw(canvas) } } }

  • Lazy Load images on Listview in android(Beginner Level)?

    - by Praveen Chandrasekaran
    Hi all, I am working on the listview with the custom adapter. I want to load the images and text view on it. The images are load from the internet urls. I just want to show the images which are visible list item to hte user. I refered the Shelves opensource project example from romainguy, but its to complicated to understand the code. For a beginner level, I just want to know how to handle the tag between the adapter and activity. From the commonsware example I can set the tag on adapter, but can't show the corresponding image at the idle state of the listview. Please help me with your ideas. Sample codes are more understandable. Thanks. EDIT: The combination of Efficient and Slow Adapter in ApiDemos is more helpful to understand.

  • How can I change the images on an ImageButton in Android when using a OnTouchListener?

    - by Cody
    I have the following code which creates an ImageButton and plays a sound when clicked: ImageButton SoundButton1 = (ImageButton)findViewById(R.id.sound1); SoundButton1.setImageResource(R.drawable.my_button); SoundButton1.setOnTouchListener(new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_DOWN ) { mSoundManager.playSound(1); return true; } return false; } }); The problem is that I want the image on the ImageButton to change when you press it. The OnTouchListener appears to be overriding the touch and not allowing the images to change. As soon as I remove the OnTouchListener, the ImageButton swaps to a different image when pressed. Any ideas on how I can have the images change on the ImageButton while still using the OnTouchListener? Thank you very much!

  • Using the public ssh key from local machine to access two remote users [closed]

    - by Nick
    I have an new Ubuntu (Hardy 8.04) server; it has two users, Alice and Bob. Alice is listed in sudoers. I appended my public ssh key (my local machine's public key local/Users/nick/.ssh/id_rsa.pub) to authorized_keys in remote_server/home/Alice/.ssh/authorized_keys, changed the permissions on Alice/.ssh/ to 700 and Alice/.ssh/authorized_keys to 600, and both the file and folder are owned my Alice. Then added I Alice to sshd_config (AllowUsers Alice). This works and I can login into Alice: ssh -v [email protected] ... debug1: Offering public key: /Users/nick/.ssh/id_rsa debug1: Server accepts key: pkalg ssh-rsa blen 277 debug1: Authentication succeeded (publickey). debug1: channel 0: new [client-session] debug1: Entering interactive session.

  • How to draw an overlay on a SurfaceView used by Camera on Android?

    - by Cristian Castiblanco
    I have a simple program that draws the preview of the Camera into a SurfaceView. What I'm trying to do is using the onPreviewFrame method, which is invoked each time a new frame is drawn into the SurfaceView, in order to execute the invalidate method which is supposed to invoke the onDraw method. In fact, the onDraw method is being invoked, but nothing there is being printed (I guess the camera preview is overwriting the text I'm trying to draw). This is a simplify version of the SurfaceView subclass I have: public class Superficie extends SurfaceView implements SurfaceHolder.Callback { SurfaceHolder mHolder; public Camera camera; Superficie(Context context) { super(context); mHolder = getHolder(); mHolder.addCallback(this); mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } public void surfaceCreated(final SurfaceHolder holder) { camera = Camera.open(); try { camera.setPreviewDisplay(holder); camera.setPreviewCallback(new PreviewCallback() { public void onPreviewFrame(byte[] data, Camera arg1) { invalidar(); } }); } catch (IOException e) {} } public void invalidar(){ invalidate(); } public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { Camera.Parameters parameters = camera.getParameters(); parameters.setPreviewSize(w, h); camera.setParameters(parameters); camera.startPreview(); } @Override public void draw(Canvas canvas) { super.draw(canvas); // nothing gets drawn :( Paint p = new Paint(Color.RED); canvas.drawText("PREVIEW", canvas.getWidth() / 2, canvas.getHeight() / 2, p); } }

  • Make Bluetooth on Android 2.1 discoverable indefinitely

    - by kanov-baekonfat
    Hello all. I'm working on a research project which involves Bluetooth and the Android OS. I need to make Bluetooth discoverable indefinitely in order for the project to continue. The Problem: Android limits discoverability to 300 seconds. I cannot ask the user every 300 seconds to turn discoverability back on as my application is designed to run in the background without disturbing the user. As far as I am aware, there is no way to increase the time though Android's GUI. Some sources have called this a safety feature, others have called this a bug. There may be a bit of truth in both... What I'm Trying / Have Tried: I'm trying to edit a stable release of cyanogenmod to turn the discoverability timer off (it's possible; there's a configuration file that needs to have a single number changed). This isn't working because I'm having verification problems with the resulting package. During the past week, I downloaded the cyanogenmod source code, changed a relevant class in the hope that it would make Bluetooth discoverable indefinitely, and tried to recompile. This did not work because (a) the repo is frequently changed, leading to an unstable code base which fails to compile (OR, it could be that I'm using it incorrectly; just because it looked like it was the code's fault in many instances doesn't mean I should blame it for all the problems I encountered!) and (b) the repo decides to periodically "ignore" me (but not always, as I have gotten the code base before!), replying to my synchronization/connection attempts with: fatal: The remote end hung up unexpectedly As you might imagine, the above two issues are problematic and very frustrating to deal with. More Info: I'm running Android 2.1 via cyanogenmod (v5 I believe). This means the phone is also rooted. I have a developer phone, which means that the bootloader is unlocked. My phone is an HTC Magic (32B). The Big Question: How can I make Bluetooth indefinitely discoverable on Android? Thanks for your time and input. I feel like I'm spinning my tires on this issue and I'd like to move past it.

  • ArrayIndexOutOfBoundsException with custom Android Adapter for multiple views in ListView

    - by Dan Watling
    I am attempting to create a custom Adapter for my ListView since each item in the list can have a different view (a link, toggle, or radio group), but when I try to run the Activity that uses the ListView I receive an error and the app stops. The application is targeted for the Android 1.6 platform. The code: public class MenuListAdapter extends BaseAdapter { private static final String LOG_KEY = MenuListAdapter.class.getSimpleName(); protected List<MenuItem> list; protected Context ctx; protected LayoutInflater inflater; public MenuListAdapter(Context context, List<MenuItem> objects) { this.list = objects; this.ctx = context; this.inflater = (LayoutInflater)this.ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } @Override public View getView(int position, View convertView, ViewGroup parent) { Log.i(LOG_KEY, "Position: " + position + "; convertView = " + convertView + "; parent=" + parent); MenuItem item = list.get(position); Log.i(LOG_KEY, "Item=" + item ); if (convertView == null) { convertView = this.inflater.inflate(item.getLayout(), null); } return convertView; } @Override public boolean areAllItemsEnabled() { return false; } @Override public boolean isEnabled(int position) { return true; } @Override public int getCount() { return this.list.size(); } @Override public MenuItem getItem(int position) { return this.list.get(position); } @Override public long getItemId(int position) { return position; } @Override public int getItemViewType(int position) { Log.i(LOG_KEY, "getItemViewType: " + this.list.get(position).getLayout()); return this.list.get(position).getLayout(); } @Override public int getViewTypeCount() { Log.i(LOG_KEY, "getViewTypeCount: " + this.list.size()); return this.list.size(); } } The error I receive: java.lang.ArrayIndexOutOfBoundsException at android.widget.AbsListView$RecycleBin.addScrapView(AbsListView.java:3523) at android.widget.ListView.measureHeightOfChildren(ListView.java:1158) at android.widget.ListView.onMeasure(ListView.java:1060) at android.view.View.measure(View.java:7703) I do know that the application is returning from getView and everything seems in order. Any ideas on what could be causing this would be appreciated. Thanks, -Dan

  • ClassCastException when casting custom View subclass

    - by Jens Jacob
    Hi I've run into an early problem with developing for android. I've made my own custom View (which works well). In the beginning i just added it to the layout programmatically, but i figured i could try putting it into the XML layout instead (for consistency). So what i got is this: main.xml: [...] <sailmeter.gui.CompassView android:id="@+id/compassview1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/widget55" android:background="@color/white" /> [...] CompassView.java: public class CompassView extends View { } SailMeter.java (activity class): public class SailMeter extends Activity implements PropertyChangeListener { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); compassview = (CompassView) findViewById(R.id.compassview1); [...] } } (Theres obviously more, but you get the point) Now, this is the stacktrace: 05-23 16:32:01.991: ERROR/AndroidRuntime(10742): Uncaught handler: thread main exiting due to uncaught exception 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): java.lang.RuntimeException: Unable to start activity ComponentInfo{sailmeter.gui/sailmeter.gui.SailMeter}: java.lang.ClassCastException: android.view.View 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2596) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2621) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.access$2200(ActivityThread.java:126) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1932) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.os.Handler.dispatchMessage(Handler.java:99) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.os.Looper.loop(Looper.java:123) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.main(ActivityThread.java:4595) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at java.lang.reflect.Method.invokeNative(Native Method) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at java.lang.reflect.Method.invoke(Method.java:521) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at dalvik.system.NativeStart.main(Native Method) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): Caused by: java.lang.ClassCastException: android.view.View 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at sailmeter.gui.SailMeter.onCreate(SailMeter.java:51) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2544) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): ... 11 more Why cant i cast my custom view? I need it to be that type since it has a few extra methods in it that i want to access. Should i restructure it and have another class handle the logic, and then just having the view being a view? Thanks for any help.

  • Android java.lang.VerifyError for private method with annotated argument.

    - by alex2k8
    I have a very simple project that compiles, but can't be started on Emulator. The problem is with this method: private void bar(@Some String a) {} // java.lang.VerifyError The issue can be avoided if annotation removed private void bar(String a) {} // OK or the method visibility changed: void bar(@Some String a) {} // OK public void bar(@Some String a) {} // OK protected void bar(@Some String a) {} // OK Any idea what is wrong with original method? Is this a dalvik bug, or? If some one whould like to experiment with code, here it is: Test.java: public class Test { private void bar(@Some String a) {} public void foo() { bar(null); } } Some.java: public @interface Some {} MainActivity.java: public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); new Test().foo(); } } Stack trace: ERROR/dalvikvm(1358): Could not find method com.my.Test.bar, referenced from method com.my.Test.foo WARN/dalvikvm(1358): VFY: unable to resolve direct method 11: Lcom/my/Test;.bar (Ljava/lang/String;)V WARN/dalvikvm(1358): VFY: rejecting opcode 0x70 at 0x0001 WARN/dalvikvm(1358): VFY: rejected Lcom/my/Test;.foo ()V WARN/dalvikvm(1358): Verifier rejected class Lcom/my/Test; DEBUG/AndroidRuntime(1358): Shutting down VM WARN/dalvikvm(1358): threadid=3: thread exiting with uncaught exception (group=0x4000fe70) ERROR/AndroidRuntime(1358): Uncaught handler: thread main exiting due to uncaught exception ERROR/AndroidRuntime(1358): java.lang.VerifyError: com.my.Test ERROR/AndroidRuntime(1358): at com.my.MainActivity.onCreate(MainActivity.java:13) ERROR/AndroidRuntime(1358): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1123) ERROR/AndroidRuntime(1358): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2231) ERROR/AndroidRuntime(1358): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2284) ERROR/AndroidRuntime(1358): at android.app.ActivityThread.access$1800(ActivityThread.java:112) ERROR/AndroidRuntime(1358): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1692) ERROR/AndroidRuntime(1358): at android.os.Handler.dispatchMessage(Handler.java:99) ERROR/AndroidRuntime(1358): at android.os.Looper.loop(Looper.java:123) ERROR/AndroidRuntime(1358): at android.app.ActivityThread.main(ActivityThread.java:3948) ERROR/AndroidRuntime(1358): at java.lang.reflect.Method.invokeNative(Native Method) ERROR/AndroidRuntime(1358): at java.lang.reflect.Method.invoke(Method.java:521) ERROR/AndroidRuntime(1358): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:782) ERROR/AndroidRuntime(1358): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:540) ERROR/AndroidRuntime(1358): at dalvik.system.NativeStart.main(Native Method)

  • How to open a nested child PreferenceScreen in Android.

    - by Mike
    Hello, I have a PreferenceScreen that is defined in XML that serves all the preferences for my application. This PreferenceScreen also has a child PreferenceScreen nested within it. My implementing class is called PreferencesActivity. I know I can open the main Preferences window via startActivity(new Intent(this, PreferencesActivity.class)); but how do I go about opening the child PreferenceScreen via an Intent?

  • Android: Is it better to start and stop a service each time it is needed or to let a service run and

    - by Flo
    I'm developing an app that checks several conditions during an incoming phone call. The main parts of the app are a BroadcastReceiver listening for Intents related to the phone's status and a local Service checking the conditions. At the moment the service is started each time an incoming call is detected and is stopped when the phone status changed back to idle. Now I'm wondering if this procedure is correct and whether it is reasonable to start and stop the service related to the phone's status. Or would it be better to let the service run regardless of the phone's status and bind/unbind to/from it when needed. Are there any performance issues I would have to think about? Perhaps it is more expensive to start/stop a service than letting it run and communicate with it. Are there any best practices out there regarding the implementation of services?
