implement CameraPickerClass.CameraPickerMethod in your activity or fragment

@Override
public void fileUrl(File file) {
   chatStatus.setText("Please wait file uploading...");        
}

@Override

public void fileUrl(File file) {

chatStatus.setText("Please wait file uploading...");

}

initlize object

private CameraPickerClass cameraPickerClass;
cameraPickerClass = new CameraPickerClass(this, this);

1 2	private CameraPickerClass cameraPickerClass; cameraPickerClass = new CameraPickerClass(this, this);

call

cameraPickerClass.openPicker();

1	cameraPickerClass.openPicker();

add in AndroidManifest.xml

<provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="${applicationId}.provider"
            android:exported="false"

    <root-path name="root" path="." />
</paths>

<?xml version="1.0" encoding="utf-8"?>

in onActivityResult

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (cameraPickerClass != null)

}

in onActivityResult

@Override

public void onActivityResult(int requestCode, int resultCode, Intent data) {
