Android Custom Permissions

Understanding Android's custom permissions, here's a piece of code. Including two Android projects, Project 2 attempted to invoke the privileged activity privactivity in Project 1. Android Project 1:

Application Name:custom Permission

Pacakage Name:com.cust.perm

1) Privileged Activities Privactivity.java

Package Com.cust.perm;import android.app.activity;import android.os.bundle;/** * Created by LSC on 14-11-4.        */public class Privactivity extends Activity {@Override protected void onCreate (Bundle savedinstancestate) {        Super.oncreate (savedinstancestate);    Setcontentview (R.LAYOUT.ACTIVITY_PRIV); }}

2) Layout file Activity_priv.xml

<?xml version= "1.0" encoding= "Utf-8"? ><linearlayout xmlns:android= "http://schemas.android.com/apk/res/ Android "android:orientation=" vertical "android:layout_width=" match_parent "android:layout_height=" Match_parent "&    Gt <textview android:layout_height= "wrap_content" android:layout_width= "fill_parent" android:text= "He Llo from Privactivity "android:textsize=" 20DP "/></linearlayout>

3) configuration file Androidmanifest.xml, where the <permission .../> part is a declaration of the custom permissions, With the permission name Syh.permission.STARTMYACTIVITY, which is called later in Project2 to invoke the privileged activity privactivity, you need to get the custom permission in the configuration file with that permission name.

<?xml version= "1.0"  encoding= "Utf-8"? ><manifest xmlns:android= "http// Schemas.android.com/apk/res/android "    package=" Com.cust.perm "     Android:versioncode= "1"     android:versionname= "1.0"  >    < uses-sdk        android:minsdkversion= "7"          android:targetsdkversion= " />    <application "        android:allowbackup= "true"          android:icon= "@drawable/ic_launcher"         android:label= "@ String/app_name "        android:theme=" @style/apptheme " >         <activity             android:name= "Com.cust. Perm. Custpermmainactivity "            android:label=" @ String/app_name " >            < intent-filter>                 <action android:name= "Android.intent.action.MAIN"  />                 <category android:name= " Android.intent.category.LAUNCHER " />             </intent-filter>        </activity>         <activity android:name= ". Privactivity ">            <intent-filter>              &nBsp;  <action android:name= "Android.intent.action.MAIN"/>             </intent-filter>         </activity>    </application>        <permission        android:name= "Syh.permission.STARTMYACTIVITY"         android:protectionlevel= "Normal"          android:label= "Start my activity"          android:description= "@string/startmyactivitydesc" ></permission></manifest>

Android Project 2 (client):

Application Name:clientofcustompermission

Package Name:com.client.cust.perm

1) Activity Clientcustpermmainactivity.java

Package com.client.cust.perm;import android.app.activity;import android.content.intent;import  android.os.Bundle;import android.view.View;public class ClientCustPermMainActivity  extends activity {     @Override     protected void  OnCreate (bundle savedinstancestate)  {        super.oncreate ( Savedinstancestate);         setcontentview (R.layout.activity_ Clientcustperm)     }    //When the button is called, create a new intent, and then set the class name of the activity you want to start      public void doclick (View view) {         intent intent = new intent ();         Intent.setclassname ("Com.cust.perm", "com.cust.perm.PrivActivity");//Invoke privileged activity in Project1          startactivity (intent);     }} 

2) Layout file Activity_clientcustperm.xml

<linearlayout xmlns:android= "http:// Schemas.android.com/apk/res/android "    xmlns:tools=" Http://schemas.android.com/tools "     android:layout_width= "Match_parent"     android:layout_height= " Match_parent "    android:orientation=" vertical "    android:layout_ Margin= "20DP"     tools:context= ". Clientcustpermmainactivity$placeholderfragment ">    <Button         android:layout_height= "Wrap_content"          Android:layout_width= "Fill_parent"         android:text= "Launch  Privactivity "        android:id=" @+id/btn "         android:onclick= "DoClick"/></LINEARLAYOUT> 

3) profile configuration file Androidmanifest.xml, where <uses-permission android:name= "Syh.permission.STARTMYACTIVITY"/> Declare this activity get custom permissions, you can call the privileged activity in Project1 with this phrase

<?xml version= "1.0"  encoding= "Utf-8"? ><manifest xmlns:android= "http// Schemas.android.com/apk/res/android "    package=" Com.client.cust.perm "     android:versioncode= "1"     android:versionname= "1.0"  >     <uses-sdk        android:minsdkversion= "7"          android:targetsdkversion= " />    <application"         android:allowbackup= "true"          android:icon= "@drawable/ic_launcher"         android:label= "@string/app_name"         android:theme= "@style/apptheme"  >         <activity             android:name= "COm.client.cust.perm.ClientCustPermMainActivity "             android:label= "@string/app_name"  >             <intent-filter>                 <action android:name= "Android.intent.action.MAIN"  />                 <category android: Name= "Android.intent.category.LAUNCHER"  />             </intent-filter>        </activity>     </application>    <uses-permission android:name= " Syh.permission.STARTMYACTIVITY "/></manifest>
