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();
}
}
