1、如果在一個進程中啟動另外一個進程的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();    }}

現在我們在另外一個進程之中啟動商密的Main2Activity

只需要下面的代碼：

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");    }}

這裡就可以啟動了。

現在我們在Main2Activity中添加自訂許可權

<?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>

啟動端如果不進行配置，就會奔潰，啟動者的

MainActivity 資訊清單檔需要對上面的許可權進行配置

<?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>

然後在使用下面的代碼進行啟動：

 Intent intent = new Intent();                intent.setAction("com.weiyuan.test");                startActivity(intent);
