Posted 2020-09-03 夏叶星空

1.输入*#*#1001#*#*就可以启动某个应用

2.androidManifest.xml配置

<application  
        android:icon="@drawable/ic_launcher"  
        android:label="@string/app_name"  
        android:theme="@style/AppTheme" >  
        <activity  
            android:name=".MainActivity"  
            android:label="@string/title_activity_main" >  
            <intent-filter>  
                <action android:name="android.intent.action.MAIN" />  
  
                <category android:name="android.intent.category.LAUNCHER" />  
            </intent-filter>  
        </activity>  
        <receiver android:name="Cipher">    
            <intent-filter android:label="@string/hello_world">  
                <action android:name="android.provider.Telephony.SECRET_CODE"/>    
                <!-- *#*#1001#*#* -->    
                <data android:scheme="android_secret_code" android:host="1001"/>    
            </intent-filter>    
        </receiver>  
    </application>  

　　

3.java代吗

package com.example.anma;  
  
import android.annotation.SuppressLint;  
import android.content.BroadcastReceiver;  
import android.content.Context;  
import android.content.Intent;  
  
@SuppressLint("ParserError")  
public class Cipher extends BroadcastReceiver {  
  
    @Override  
    public void onReceive(Context arg0, Intent arg1) {  
        if (arg1.getAction().equals  
  
        ("android.provider.Telephony.SECRET_CODE")) {  
            Intent i = new Intent(Intent.ACTION_MAIN);  
            i.setClass(arg0, MainActivity.class);  
            i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  
            arg0.startActivity(i);  
        }  
    }  
  
}
