AndroidStudio 2.1.2: Error:Execution failed for task ':app:compileReleaseJavaWithJavac'

Question

MainActivity.java contains:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void submitOrder(View view) {
        display(1);
    }

    private void display(int number) {
        TextView quantityTextView = (TextView) findViewById(R.id.quantity_text_view);
        quantityTextView.setText("" + number);
    }
}

What is the reason for the compile error?

gradle.build:

apply plugin: 'com.android.application'

android { compileSdkVersion 24 buildToolsVersion "24.0.1"

defaultConfig {
    applicationId "com.example.android.justjava"
    minSdkVersion 15
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

}

dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) testCompile 'junit:junit:4.12' compile 'com.android.support:appcompat-v7:24.1.1' }

I have already tried: clean/rebuild project.

Answer 1

its issues around your compileSdkVersion and buildToolVersion change it in your gradle file and you should be fine. compileSdkVersion 24 buildToolsVersion '24.0.0'

you can as well update your targetSdkVersion to 24
