[kubraozer]

`
import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;
...

@TargetApi(23)
private void openCameraWithPermission() {
if (ContextCompat.checkSelfPermission(this.activity, Manifest.permission.CAMERA)
== PackageManager.PERMISSION_GRANTED) {
barcodeView.resume();
} else if(!askedPermission) {
ActivityCompat.requestPermissions(this.activity,
new String[]{Manifest.permission.CAMERA},
cameraPermissionReqCode);
askedPermission = true;
} else {
// Wait for permission result
}
}
`

In my gradle;
minSdkVersion 19
targetSdkVersion 23
versionCode 22

compile 'com.android.support:support-v4:24.0.0'

I use;
zxing-android-embeded-3.2.0

Stack Trace
java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v4/content/ContextCompat;
at com.journeyapps.barcodescanner.CaptureManager.openCameraWithPermission(CaptureManager.java:233)

Cannot resolved ContextCompat and ActivityCompat. My device is android 6.0.0. What should ı do for this error?
