我的Android应用程序中可以有多个getIntent（）方法吗？

Question

I want to receive an intent from my applications first activity to second and also from some other application in the same (Second activity).

Can it be done?

Answer 1

The Intent represents an app's "intent to do something.", and every Activity is invoked by an Intent.

Your SecondActivity will be started with you start an implicit or explicit intent.

You wanna your SecondActivity to be started from your Activity or from other app, you need to define a custom Action for this.

<activity android:name=".SecondActivity" >  
<intent-filter>
    <action android:name="com.example.DO_SOME_ACTION" />
    <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

You be able to start your Activity from any application like this :

Intent intent = new Intent();
intent.setAction("com.example.DO_SOME_ACTION");
startActivity(intent);
