MultiDex stopped working Android

MultiDex stopped working Android - java

last night I was working on my app, initially I already reached my 64k limit so have had multidex for sometime now, sometimes it does fail and gives me a ClassNotFoundException but all I do is recompile my code and it works, if it fails I restart my computer but this time it is a different case, MultiDex seems to be excluding one of my classes which is funny because it was working until it suddenly stop, what it is doing it is excluding my EnhancedGallery.class which am using as my start activity, if I change to some other activity as start activity in manifest the App works until I try to run EnhancedGallery below are my Gradle Configurations

It has been a hustle, I finally fix it, or should I say found a way of bypassing it, since other classes were working I just created another class and copy pasted all my lines of code to the new class and it worked, I do not know the attachment between MultiDex and my EnhancedGallery class yet.

https://stackoverflow.com/questions/50453822/room-cannot-find-implementation-db-db-impl-does-not-exist
But none is working because I'm using Java not Kotlin. Many of the solutions above suggested change the annotationProcessor to kapt then add apply plugin: 'kotlin-kapt' but it'll only give another error

I missed the #Database annotation right before the abstract class WordRoomDatabase. After adding #Database(entities = {Word.class}, version = 1, exportSchema = false), everything works fine.

In my case, annotations were fine but I had issue with Gradle dependencies. So make sure that you have at lease these too:
implementation "androidx.room:room-ktx:$rootProject.roomVersion"
kapt "androidx.room:room-compiler:$rootProject.roomVersion"
And also you should have id 'kotlin-kapt' in your plugins brackets.

my app does not have any errors when it builds, however, it stops working when I run it on my phone, and when I open the app it stopped working and then I decided to run it in the debug and see the errors that have in it through logcat

I solved this problem by pass instance the activity instead of the context to PopupMenu();

java.lang.NoSuchFieldError: android.support.v4.app.Watson.mFragments

I'm trying to implement ActionBarSherlock swipe menu as I like how this animation slides over the slide menu. Unfortunately I keep getting this error and haven't been able to solve it.
This guy is getting the same error but none of the answers on this solves my problem. Android: java.land.NoSuchFieldError after update to SDK 23

I was able to solve the problem by removing the facebook sdk from my gradle file. Since i need the facebook sdk, i was able to get around this by making MainActivity just extend FragmentActivity instead of SlidingFragmentActivty. I made this inner class inside of MainActivty to extend SlidingActivity, that way i can still use the methods i need.
private class SlidingMenuClass extends SlidingActivity {
private SlidingMenu sm;
public SlidingMenuClass(Context ctx){
sm = new SlidingMenu(ctx);
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setBehindContentView(R.layout.menu_frame);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
sm = getSlidingMenu();
sm.attachToActivity(this, SlidingMenu.SLIDING_CONTENT);
sm.setShadowWidthRes(R.dimen.shadow_width);
//sm.setShadowDrawable(R.drawable.shadow);
sm.setFadeDegree(1f);
sm.setTouchModeAbove(SlidingMenu.TOUCHMODE_MARGIN);
sm.setBehindOffsetRes(R.dimen.behindoffsetRes);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
toggle();
return true;
}
return super.onOptionsItemSelected(item);
}
}

okay here is my code. I am form germany and so lots of Names are german (i hope thats not a problem.
Maybe it helps.
I guess the error must be in the main activity in one of the toasts. But dont hesitate to look at the other lines.

A/c to logcat error your are getting null reference error. try to update this line
Toast.makeText(parent.getContext(),
"Deine Auswahl ist:" + parent.getItemAtPosition(position).toString(), Toast.LENGTH_SHORT).show();
with the following code
Toast.makeText(MainActivity.this,
"Deine Auswahl ist:" + parent.getItemAtPosition(position).toString(), Toast.LENGTH_SHORT).show();

You have not initialised your adapter namely "klassen_adapter" in your main activity. It's null and invoking any method on it will be null pointer exception

MultiDex stopped working Android - java

It has been a hustle, I finally fix it, or should I say found a way of bypassing it, since other classes were working I just created another class and copy pasted all my lines of code to the new class and it worked, I do not know the attachment between MultiDex and my EnhancedGallery class yet.
