I have a task to create an android application that has a one button and it will run an another android application. But I'm not the one who created that another application, so I did some research for my first android app. I found that I need to get the package and class name of the app to run the other application, so I got a third party application to get the package and class name of an app. This is the code and it works:
public class MainActivity extends AppCompatActivity {
private String pckage_name = "com.sample.package";
private String clss_name = "com.sample.function.class";
private Button bt;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bt = (Button) findViewById(R.id.button);
bt.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
launchCall();
}
});
}
private void launchCall() {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.setComponent(new ComponentName(pckage_name, clss_name));
try {
startActivity(intent);
} catch (Exception e) {
e.printStackTrace();
}
}
}
When that app opens, it has buttons that I need to click so it functions will run, but what I'm trying to do is to run that automatically from my app with just one click of a button. I don't know if the other class name is the one I'll use to run the buttons automatically using my app, or is it wrong?
