Issue in resolving nonnull and notnull symbol in looper.java

Question

I\'m developing an android app please help me to solve dependency error.

package android.os;
import android.support.annotation.NonNull;
import android.suppor         


        

Answer 1

Since Google announced at IO17 gradle:3.0, the compile configuration is now deprecated and should be replaced by implementation or api

So prefer

dependencies {
    ...
    implementation 'com.android.support:support-annotations:27.1.1'
    ...
}

or greater version
