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() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
// 获取到进程B中的binder对象
iLogin = ILoginInterface.Stub.asInterface(service);
}
@Override
public 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.aidl
package com.example.process;
// Declare any non-default types here with import statements
interface 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\">
<application
android: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() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
iLogin = ILoginInterface.Stub.asInterface(service);
}
@Override
public 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);
}
}
}
对应界面
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
<application
android: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>
