Use custom Permissions in Android

1. If the activity of another process is initiated in one process

<?XML version= "1.0" encoding= "Utf-8"?><Manifestxmlns:android= "Http://schemas.android.com/apk/res/android" Package= "Im.weiyuan.com.hkkj">    <ApplicationAndroid:allowbackup= "true"Android:icon= "@mipmap/ic_launcher"Android:label= "@string/app_name"Android:supportsrtl= "true"Android:theme= "@style/apptheme">        <ActivityAndroid:name=". Mainactivity ">            <Intent-filter>                <ActionAndroid:name= "Android.intent.action.MAIN" />                <categoryAndroid:name= "Android.intent.category.LAUNCHER" />            </Intent-filter>        </Activity>        <ActivityAndroid:name=". Main2activity ">            <Intent-filter>                <ActionAndroid:name= "Com.weiyuan.test"></Action>                <categoryAndroid:name= "Android.intent.category.DEFAULT"></category>            </Intent-filter>        </Activity>    </Application></Manifest>

Package Im.weiyuan.com.hkkj;import Android.support.v7.app.appcompatactivity;import Android.os.bundle;import Android.widget.toast;public class Main2activity extends Appcompatactivity {    @Override    protected void onCreate (Bundle savedinstancestate) {        super.oncreate (savedinstancestate);        Setcontentview (r.layout.activity_main2);        Toast.maketext (Main2activity.this, "JKSAJKDJK", Toast.length_long). Show ();    }}

Now we're starting the main2activity in another process.

Only the following code is required:

 Packageim.weiyuan.com.viewutils;Importandroid.content.Intent;ImportAndroid.os.PersistableBundle;Importandroid.support.v7.app.AppCompatActivity;ImportAndroid.os.Bundle;ImportAndroid.util.Log;ImportAndroid.view.View;ImportAndroid.widget.Button;ImportAndroid.widget.TextView;ImportAndroid.widget.Toast; Public classMainactivityextendsappcompatactivity {PrivateButton Btn_main; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);         Setcontentview (R.layout.activity_main); if(Savedinstancestate! =NULL) {Toast.maketext (mainactivity. This, savedinstancestate.getstring ("Data"), Toast.length_long). Show (); } Btn_main=(Button) Findviewbyid (R.id.btn_main); Btn_main.setonclicklistener (NewView.onclicklistener () {@Override Public voidOnClick (View v) {Intent Intent=NewIntent (); Intent.setaction ("Com.weiyuan.test");            StartActivity (Intent);    }        }); } @Overrideprotected voidOnStop () {Super. OnStop (); LOG.D ("123456", "OnStop is called"); } @Overrideprotected voidOnPause () {Super. OnPause (); LOG.D ("123456", "OnPause is called"); } @Override Public voidonsaveinstancestate (Bundle outstate) {Super. Onsaveinstancestate (outstate); LOG.D ("123456", "Onsaveinstancestate is called"); Outstate.putstring ("Data", "1020223"); }}

Here it's ready to start.

Now we add custom permissions in Main2activity

<?XML version= "1.0" encoding= "Utf-8"?><Manifestxmlns:android= "Http://schemas.android.com/apk/res/android" Package= "Im.weiyuan.com.hkkj">    <ApplicationAndroid:allowbackup= "true"Android:icon= "@mipmap/ic_launcher"Android:label= "@string/app_name"Android:supportsrtl= "true"Android:theme= "@style/apptheme">        <ActivityAndroid:name=". Mainactivity ">            <Intent-filter>                <ActionAndroid:name= "Android.intent.action.MAIN" />                <categoryAndroid:name= "Android.intent.category.LAUNCHER" />            </Intent-filter>        </Activity>        <ActivityAndroid:name=". Main2activity " android:permission= "COM.WEIYUAN.SB"             >            <Intent-filter>                <ActionAndroid:name= "Com.weiyuan.test"></Action>                <categoryAndroid:name= "Android.intent.category.DEFAULT"></category>            </Intent-filter>        </Activity>    </Application></Manifest>

Start-up if not configured, it will crash, the initiator's

The mainactivity manifest file needs to be configured with the above permissions

<?XML version= "1.0" encoding= "Utf-8"?><Manifestxmlns:android= "Http://schemas.android.com/apk/res/android" Package= "Im.weiyuan.com.viewutils"> <permission  android:name= "COM.WEIYUAN.SB"></  Permission><uses-permission  android:name= "COM.WEIYUAN.SB"  ></uses-permission>         <ApplicationAndroid:allowbackup= "true"Android:icon= "@mipmap/ic_launcher"Android:label= "@string/app_name"Android:supportsrtl= "true"Android:theme= "@style/apptheme">        <ActivityAndroid:name=". Mainactivity ">            <Intent-filter>                <ActionAndroid:name= "Android.intent.action.MAIN" />                <categoryAndroid:name= "Android.intent.category.LAUNCHER" />            </Intent-filter>        </Activity>    </Application></Manifest>

Then start with the following code:

Intent Intent = new Intent ();                Intent.setaction ("Com.weiyuan.test");                StartActivity (intent);
