I have updated my app today and after that I got 12 crash reports. As i can see all are tide to my main activity class. Here's couple of them:
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{rs.androidaplikacije.zastaveigradovi/rs.androidaplikacije.zastaveigradovi.MainActivity}: java.lang.ClassNotFoundException: rs.androidaplikacije.zastaveigradovi.MainActivity in loader dalvik.system.PathClassLoader[/data/app/rs.androidaplikacije.zastaveigradovi-1.apk]

And here's my main activity. I did not change anything in it at all.
public class MainActivity extends SwarmActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
preload(this, 5259, "0d2ab20831857f730c1c362705970d1f");
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread splashTimer = new Thread(){
public void run(){
try {
sleep(2000);
Intent menuIntent = new Intent("rs.androidaplikacije.zastaveigradovi.MENU");
startActivity(menuIntent);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
finally{
finish();
}
}
};
splashTimer.start();
}
private void preload(MainActivity mainActivity, int i, String string) {
// TODO Auto-generated method stub
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
Everything works fine on my phone, but i got a lot of crash reports today. Can someone tell me what's the problem?
SwarmActivity? If any of the superclasses depend on a class that doesn't exist on someone's phone, then this error will be thrown. If they merely REFER to another class, the class can't load. (worst case: you may have to use dynamic class loading via reflection).
