[SOLVED] Android app failed to Init in android API level 21 but successed in API level 31

Massdrive · May 6, 2023, 3:22am

Hi, guys. I just got a weird problem:

My program is a simple Android app, a Box with Unshaded material.

Material mat0 = new Material(app.getAssetManager(), "Common/MatDefs/Misc/Unshaded.j3md");
mat0.setColor("Color", ColorRGBA.Blue);
...
geomBox.setMaterial(mat0);

It works in Android studio’s emulator at api level 31 BUT failed in api level 21.
For hardwares, It passed in a device with api 29 (a xiaomi phone), failed in api 23 (a Samsung phone).
Android studio error message is shown below:

Do you have library desugaring enabled?

Massdrive · May 6, 2023, 5:44am

Thanks Ali_RS
problem solved.

compileSdk 31
...
minSdk 21

compileOptions {
        coreLibraryDesugaringEnabled true
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
...
 coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.2.2'

BUT I may found an even weirder problem , I’ll post it in another thread.

My android studio only have 1.2.2 and 1.1.5 on the list in files–>project structure -->dependences
because of “minSdk 21”, maybe?
