I have an app that has a bottom bar with three fragments. There are also a few child fragments that are being called from parent fragments. Google Play console shows several crashes due to java.lang.IllegalArgumentException. I cannot seem to replicate the error, and nothing points to my code in the logs.
Can anybody decipher what could be the problem? Here is the error stack trace. java.lang.RuntimeException: at android.app.ActivityThread.performLaunchActivity (ActivityThread.java:3190) at android.app.ActivityThread.handleLaunchActivity (ActivityThread.java:3300) at android.app.ActivityThread.access$1000 (ActivityThread.java:211) at android.app.ActivityThread$H.handleMessage (ActivityThread.java:1705) at android.os.Handler.dispatchMessage (Handler.java:102) at android.os.Looper.loop (Looper.java:145) at android.app.ActivityThread.main (ActivityThread.java:6946) at java.lang.reflect.Method.invoke (Native Method) at java.lang.reflect.Method.invoke (Method.java:372) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run (ZygoteInit.java:1404) at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:1199) Caused by: java.lang.IllegalArgumentException: at android.support.v4.app.FragmentManagerImpl.moveToState (FragmentManager.java:1293) at android.support.v4.app.FragmentManagerImpl.moveFragmentToExpectedState (FragmentManager.java:1528) at android.support.v4.app.FragmentManagerImpl.moveToState (FragmentManager.java:1595) at android.support.v4.app.BackStackRecord.executeOps (BackStackRecord.java:758) at android.support.v4.app.FragmentManagerImpl.executeOps (FragmentManager.java:2363) at android.support.v4.app.FragmentManagerImpl.executeOpsTogether (FragmentManager.java:2149) at android.support.v4.app.FragmentManagerImpl.optimizeAndExecuteOps (FragmentManager.java:2103) at android.support.v4.app.FragmentManagerImpl.execPendingActions (FragmentManager.java:2013) at android.support.v4.app.FragmentController.execPendingActions (FragmentController.java:388) at android.support.v4.app.FragmentActivity.onStart (FragmentActivity.java:607) at android.support.v7.app.AppCompatActivity.onStart (AppCompatActivity.java:178) at android.app.Instrumentation.callActivityOnStart (Instrumentation.java:1264) at android.app.Activity.performStart (Activity.java:6613) at android.app.ActivityThread.performLaunchActivity (ActivityThread.java:3153) Shown below is the launcher activity code public void onMenuItemSelected(int itemId) {Fragment fragment;switch (itemId) { case R.id.home: fragment = new HomeFragment(); if (fragment != null) { getSupportFragmentManager().beginTransaction() .replace(R.id.content_frame, fragment).commit(); }else { } break; case R.id.profile: fragment = new ProfileFragment(); if (fragment != null) { getSupportFragmentManager().beginTransaction() .replace(R.id.content_frame, fragment).commit(); }else { } break; case R.id.account: fragment = new AccountMainFragment(); if (fragment != null) { getSupportFragmentManager().beginTransaction() .replace(R.id.content_frame, fragment).commit(); }else { //Log.e("MainActivity", "Error in creating fragment"); } break;} When i'm inside a fragment and want to switch to another fragment, this is the code: SingleProductFragment fragment = new SingleProductFragment(); fragment.setArguments(bundle);FragmentManager fragmentManager = (((AppCompatActivity) context).getSupportFragmentManager()); FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); fragmentTransaction.addToBackStack("single"); fragmentTransaction.replace(R.id.content_frame, fragment); fragmentTransaction.commit(); When inside a activity and need to call an activity, I do it through the main activity : Intent intent = new Intent(NotificationListViewActivity.this, AppMainActivity.class); intent.putExtra("FragmentCheck", "single"); startActivity(intent); -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
