Android Chartboost SDK Error

Question

I have the next error with my app with Chartboost sdk integrated: my app runs fine and show static and video interstitial, I can launch my app several times and always ads show fine but when exit the app and with Android recents button if I close my app then my app crashes on launch (I initialize the Chartboost SDK on Main activity app launch) but if I quit Chartboost sdk then this behaviour does not happen. Does the same thing happen to your apps? see image bellow, thanks.

Answer 1

the error message refers to the support libraries, which would need to be >= version 23.0.0. this issue can be fixed with the module-level build-gradle and these dependencies:

implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:support-v4:27.1.1'

and you'd have to implement the below methods, in order to forward the interface methods:

@Override
public void onStart() {
    super.onStart();
    Chartboost.onStart(this);
}

@Override
public void onResume() {
    super.onResume();
    Chartboost.onResume(this);
}

@Override
public void onPause() {
    super.onPause();
    Chartboost.onPause(this);
}

@Override
public void onStop() {
    super.onStop();
    Chartboost.onStop(this);
}

@Override
public void onDestroy() {
    super.onDestroy();
    Chartboost.onDestroy(this);
}

@Override
public void onBackPressed() {
    // If an interstitial is on screen, close it.
    if (Chartboost.onBackPressed()) {
        return;
    } else {
        super.onBackPressed();
    }
}

here it is basically all explained in detail ...eg. Android API level 27 is not yet being support - therefore API level 26 is the maximum level available (but one can still use those 27.1.1 support libraries).

In every case, the stack-trace and the error description do not match, at all.
