详解Android跨进程通信之AIDL

需求描述

进程A调起第三方进程B进行第三方登录 ? 实现双向通信

代码（进程A）1.目录结构

2.LoginActivity.java

public class LoginActivity extends AppCompatActivity { private ILoginInterface iLogin; @Override protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);initService(); } private void initService() {// 绑定进程B中的服务Intent intent = new Intent();intent.setAction('ACTION_B');intent.setPackage('com.example.processs');bindService(intent, conn, BIND_AUTO_CREATE); } private ServiceConnection conn = new ServiceConnection() {@Overridepublic void onServiceConnected(ComponentName name, IBinder service) { // 获取到进程B中的binder对象 iLogin = ILoginInterface.Stub.asInterface(service);}@Overridepublic void onServiceDisconnected(ComponentName name) {} }; /** * 去登录 * * @param view */ public void goLogin(View view) {try { if (iLogin != null) {iLogin.login(); } else {Toast.makeText(this, '未安装第三方应用啊~', Toast.LENGTH_SHORT).show(); }} catch (RemoteException e) { e.printStackTrace();} } @Override protected void onDestroy() {super.onDestroy();if (iLogin != null) { unbindService(conn);} }}

对应界面

3. ILoginInterface.aidl

// ILoginInterface.aidlpackage com.example.process;// Declare any non-default types here with import statementsinterface ILoginInterface { void login(); void loginCallback(int loginStatus, String loginUser);}4.LoginService.java 用于进程B登录回调的Service

public class LoginService extends Service { @Nullable @Override public IBinder onBind(Intent intent) {// 该Binder对象返回给进程B来回调return new ILoginInterface.Stub() { @Override public void login() throws RemoteException { } @Override public void loginCallback(int loginStatus, String loginUser) throws RemoteException {Log.d('lichaojun123>>>', 'loginCallback: ' + loginStatus + ' : ' + loginUser); }}; }}5.AndroidManifest.xml

<?xml version='1.0' encoding='utf-8'?><manifest xmlns:android='http://schemas.android.com/apk/res/android' xmlns:tools='http://schemas.android.com/tools' package='com.example.processc'> <applicationandroid:allowBackup='true'android:icon='@mipmap/ic_launcher'android:label='@string/app_name'android:roundIcon='@mipmap/ic_launcher_round'android:supportsRtl='true'android:theme='@style/AppTheme'><activity android:name='com.example.process.LoginActivity'> <intent-filter><action android:name='android.intent.action.MAIN' /><category android:name='android.intent.category.LAUNCHER' /> </intent-filter></activity><service android:name='com.example.process.LoginService' android:enabled='true' // 是否可以被系统实例化 android:exported='true' // 是否可以被其他进程隐式调用 android:process=':remote_a'> <intent-filter><action android:name='ACTION_A'/> </intent-filter></service> </application></manifest>代码（进程B）1.目录结构

2.LoginActivity.java

public class LoginActivity extends AppCompatActivity { private EditText etName; private EditText etPwd; private ILoginInterface iLogin; @Override protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);etName = findViewById(R.id.et_name);etPwd = findViewById(R.id.et_pwd);initService(); } private void initService() {// 绑定进程A中的服务Intent intent = new Intent();intent.setAction('ACTION_A');intent.setPackage('com.example.processc');bindService(intent, conn, BIND_AUTO_CREATE); } private ServiceConnection conn = new ServiceConnection() {@Overridepublic void onServiceConnected(ComponentName name, IBinder service) { iLogin = ILoginInterface.Stub.asInterface(service);}@Overridepublic void onServiceDisconnected(ComponentName name) {} }; // 去登录 public void go_login(View view) {if (etName.getText().toString().trim().equals('lcj')&& etPwd.getText().toString().trim().equals('123')) { try {if (iLogin != null) { // 登录成功后，通知客户端进程 iLogin.loginCallback(1, '登录成功'); finish();} } catch (RemoteException e) {e.printStackTrace(); }} else { Toast.makeText(this, '登录失败', Toast.LENGTH_SHORT).show();} } @Override protected void onDestroy() {super.onDestroy();if (iLogin != null) { unbindService(conn);} }}

3. ILoginInterface.aidl (与进程A相同)4. LoginService.java 用于进程A调用的Service

public class LoginService extends Service { @Nullable @Override public IBinder onBind(Intent intent) {return new ILoginInterface.Stub() { @Override public void login() throws RemoteException {execLogin(); } @Override public void loginCallback(int loginStatus, String loginUser) throws RemoteException { }}; } private void execLogin() {// 调起登录页面Intent intent = new Intent(this, LoginActivity.class);intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);startActivity(intent); }}5.AndroidManifest.xml

<applicationandroid:allowBackup='true'android:icon='@mipmap/ic_launcher'android:label='@string/app_name'android:roundIcon='@mipmap/ic_launcher_round'android:supportsRtl='true'android:theme='@style/AppTheme'><activity android:name='.LoginActivity'> <intent-filter><action android:name='android.intent.action.MAIN' /><category android:name='android.intent.category.LAUNCHER' /> </intent-filter></activity><service android:name='.LoginService' android:enabled='true' android:exported='true' android:process=':remote_b'> <intent-filter><action android:name='ACTION_B'/> </intent-filter></service> </application>
