ClassNotFoundException: Didn't find class “android.os.PersistableBundle” Otto Android 5.0

问题

I have a strange issue. I have an app which I deployed on an Android 4.4 device and use Otto library. I deployed the app on an Android 5.0 device. It still works. I retried on the 4.4 and the app won't launched.

Apparently, it tries to use PersistableBundle.class which a API 21 class. Here my log :

    Caused by: java.lang.ClassNotFoundException: Didn't find class "android.os.PersistableBundle" on path: DexPathList[[zip file "/data/app/fr.myapp.apk"],nativeLibraryDirectories=[/data/app-lib/fr.myapp, /vendor/lib, /system/lib]]

I find the "solution". Just remove this function from your activity :

@Override
public void onSaveInstanceState(Bundle outState, PersistableBundle outPersistentState) {
    super.onSaveInstanceState(outState, outPersistentState);
}

回答2:

Change targetVersion to the API version of the device you are running.

I had targetVersion = 21 when my device had 4.4 (API 19), changing the value to 19 solved the issue.

I had a same problem on Samsung Galaxy 3mini and Local operator phones.But i fixed with override activity method.i hope it works for you.

 @Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
    try {
        BusApplication.getInstance().register(this);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Base on FAG

Some Android versions seem to have a bug with reflection when calling getDeclaredMethods or getMethods

in this case PersistableBundle was added in API level 21 and when we use it in lifecycle methods like onCreate or onSaveInstanceState this error happens.

If you use of any of following methods in your code

@Override
public void onCreate(Bundle savedInstanceState,PersistableBundle persistentState) {
    super.onCreate(savedInstanceState, persistentState);
}

@Override
public void onPostCreate(Bundle savedInstanceState,PersistableBundle persistentState) {
    super.onPostCreate(savedInstanceState, persistentState);
}

@Override
public void onRestoreInstanceState(Bundle savedInstanceState, PersistableBundle persistentState) {
    super.onRestoreInstanceState(savedInstanceState, persistentState);
}

@Override
public void onSaveInstanceState(Bundle outState, PersistableBundle outPersistentState) {
    super.onSaveInstanceState(outState, outPersistentState);
}

Use following methods instead (or remove above methods if useless)

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

@Override
public void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
}

@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
}

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
} 

In my case i use this method in baseActivity and made the crash

override fun onCreate(savedInstanceState: Bundle?, persistentState: PersistableBundle?) {
        super.onCreate(savedInstanceState, persistentState) 
}

Simply i replace this with

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
}

And problem solved.
