Download And Install apk from a link.
- by rayman
Hi,
I`am trying to download and install an apk from some link,
but for some reason i get an exception.
I have one method downloadfile() which downloading the file and a call
to and installFile() method, which supposed to install it in the device.
some code:
public void downloadFile()
{
String fileName = "someApplication.apk";
MsgProxyLogger.debug(TAG, "TAG:Starting to download");
try
{
URL u = new URL(
"http://10.122.233.22/test/someApplication.apk");
try
{
HttpURLConnection c = (HttpURLConnection) u.openConnection();
try
{
c.setRequestMethod("GET");
c.setDoOutput(true);
try
{
c.connect();
FileOutputStream f = context.openFileOutput(fileName,
context.MODE_WORLD_READABLE);
try
{
InputStream in = c.getInputStream();
byte[] buffer = new byte[1024];
int len1 = 0;
int totsize = 0;
try
{
while ((len1 = in.read(buffer)) > 0)
{
totsize += len1;
f.write(buffer, 0, len1);// .write(buffer);
}
} catch (IOException e)
{
e.printStackTrace();
}
f.close();
MsgProxyLogger.debug(TAG, TAG
+ ":Saved file with name: " + fileName);
InstallFile(fileName);
} catch (IOException e)
{
e.printStackTrace();
}
} catch (IOException e)
{
e.printStackTrace();
}
} catch (ProtocolException e)
{
e.printStackTrace();
}
} catch (IOException e)
{
e.printStackTrace();
}
} catch (MalformedURLException e)
{
e.printStackTrace();
}
}
and this is the install file method:
private void InstallFile(String fileName)
{
MsgProxyLogger.debug(TAG, TAG + ":Installing file " + fileName);
String src = String.format(
"file:///data/data/com.test/files/",
fileName);
Uri mPackageURI = Uri.parse(src);
PackageManager pm = context.getPackageManager();
int installFlags = 0;
try
{
PackageInfo pi = pm.getPackageInfo("com.mirs.agentcore.msgproxy",
PackageManager.GET_UNINSTALLED_PACKAGES);
if (pi != null)
{
MsgProxyLogger.debug(TAG, TAG + ":replacing " + fileName);
installFlags |= PackageManager.REPLACE_EXISTING_PACKAGE;
}
} catch (NameNotFoundException e)
{
}
try
{
// PackageInstallObserver observer = new PackageInstallObserver();
pm.installPackage(mPackageURI);
} catch (SecurityException e)
{
//!!!!!!!!!!!!!here i get an security exception!!!!!!!!!!!
MsgProxyLogger.debug(TAG, TAG + ":not permission? " + fileName);
}
this is the exception details:
"Neither user 10057 nor current process has android.permission.INSTALL_PACKAGES".
and i have set in my main app that permission in the manifest.
anyone has any idea?
thanks,
ray.
