Start Android APK with args from adb

Question

I'm looking for way to start my APK with args.

First, How can I get args in OnCreate method?

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

    //get args1, get  args2...
}

Then with adb, How can I run my application with those args? I just see example like that:

adb shell am start -S -D com.example.apk/android.app.MainActivity --es args '"-name MYNAME -email test@gmail.com"'

That is not possible, in the terms that you describe.

That is not possible, in the terms that you describe.

What you can do — and what the adb example shows you — is supply Intent extras:

adb shell am start -S -D com.example.apk/android.app.MainActivity --es args '"-name MYNAME -email test@gmail.com"'

This is not a particularly good way to use Intent extras, but let's start with it.

Here, you are passing a string extra named args with a value of "-name MYNAME -email test@gmail.com".

In onCreate() of your activity, you could call getIntent().getStringExtra("args") to retrieve that string:

String args = getIntent().getStringExtra("args");

Now, the args variable will hold -name MYNAME -email test@gmail.com.

A simpler and cleaner adb shell am start command would be:

adb shell am start -S -D com.example.apk/android.app.MainActivity --es name MYNAME --es email test@gmail.com

Now you are passing two string extras, name and email. You can then retrieve each value individually:

String name = getIntent().getStringExtra("name");
String email = getIntent().getStringExtra("email");
