android 中使用自定义权限

1、如果在一个进程中启动另外一个进程的activity

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="im.weiyuan.com.hkkj">

    <application

        android:allowBackup="true"

        android:icon="@mipmap/ic_launcher"

        android:label="@string/app_name"

        android:supportsRtl="true"

        android:theme="@style/AppTheme">

        <activity android:name=".MainActivity">

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

        <activity android:name=".Main2Activity">

            <intent-filter>

                <action android:name="com.weiyuan.test"></action>

                <category android: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();

    }

}

现在我们在另外一个进程之中启动商密的Main2Activity

只需要下面的代码：

package im.weiyuan.com.viewutils;

import android.content.Intent;

import android.os.PersistableBundle;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.widget.Button;

import android.widget.TextView;

import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    private  Button btn_main;

    @Override

    protected void onCreate(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(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                Intent intent = new Intent();

                intent.setAction("com.weiyuan.test");

                startActivity(intent);

            }

        });

    }

    @Override

    protected void onStop() {

        super.onStop();

        Log.d("123456","onStop is called");

    }

    @Override

    protected void onPause() {

        super.onPause();

        Log.d("123456","onPause is called");

    }

    @Override

    public void onSaveInstanceState(Bundle outState) {

        super.onSaveInstanceState(outState);

        Log.d("123456","onSaveInstanceState is called");

        outState.putString("data","1020223");

    }

}

这里就可以启动了。

现在我们在Main2Activity中添加自定义权限

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="im.weiyuan.com.hkkj">

    <application

        android:allowBackup="true"

        android:icon="@mipmap/ic_launcher"

        android:label="@string/app_name"

        android:supportsRtl="true"

        android:theme="@style/AppTheme">

        <activity android:name=".MainActivity">

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

        <activity android:name=".Main2Activity"

            android:permission="com.weiyuan.sb"

            >

            <intent-filter>

                <action android:name="com.weiyuan.test"></action>

                <category android:name="android.intent.category.DEFAULT"></category>

            </intent-filter>

        </activity>

    </application>

</manifest>

启动端如果不进行配置，就会奔溃，启动者的

MainActivity 清单文件需要对上面的权限进行配置

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns: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>

    <application

        android:allowBackup="true"

        android:icon="@mipmap/ic_launcher"

        android:label="@string/app_name"

        android:supportsRtl="true"

        android:theme="@style/AppTheme">

        <activity android:name=".MainActivity">

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

    </application>

</manifest>

然后在使用下面的代码进行启动：

 Intent intent = new Intent();

                intent.setAction("com.weiyuan.test");

                startActivity(intent);
