Android Studio的笔记--aidl实现和调用

aidl实现

新建aidl实现工程

新建一个工程。工程名testaidl。包名com.lxh.testaidl。修改配置文件

build.gradle

a
修改sdk配置，修改version，修改生成apk命名，修改编译混淆配置，增加系统签名
文件位置：\testaidl\app
文件名：build.gradle

plugins {id 'com.android.application'
}
android {compileSdkVersion 30buildToolsVersion "30.0.2"defaultConfig {applicationId "com.lxh.testaidl"minSdkVersion 28targetSdkVersion 30versionCode 1def date = new Date().format("yyyyMMddHHmm" , TimeZone.getTimeZone("GMT+08"))versionName "testaidl-V1.0-"+datetestInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"}android.applicationVariants.all {variant ->variant.outputs.all {outputFileName = new File(defaultConfig.versionName + ".apk");}}signingConfigs {release {storeFile file("../keystore/mykey.jks")storePassword '123456'keyAlias '_mykey'keyPassword '123456'}debug {storeFile file("../keystore/mykey.jks")storePassword '123456'keyAlias '_mykey'keyPassword '123456'}}buildTypes {release {minifyEnabled trueproguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'signingConfig signingConfigs.release}}compileOptions {sourceCompatibility JavaVersion.VERSION_1_8targetCompatibility JavaVersion.VERSION_1_8}
}dependencies {implementation 'androidx.appcompat:appcompat:1.2.0'implementation 'com.google.android.material:material:1.2.1'implementation 'androidx.constraintlayout:constraintlayout:2.0.1'testImplementation 'junit:junit:4.+'androidTestImplementation 'androidx.test.ext:junit:1.1.2'androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}

b
修改build variants中active build variant 从debug改成release

c
签名文件
文件位置：\testaidl\keystore
文件名：mykey.jks

proguard-rules.pro

增加混淆
文件位置：\testaidl\app
文件名：proguard-rules.pro

增加aidl文件

增加aidl文件
文件位置：testaidl\app\src\main\aidl\com\lxh\testaidl\aidl
文件名：UST.aidl

package com.lxh.testaidl.aidl;interface UST {int installPackage(String filepath,int indicator,String version);}

增加aidl实现

编译一遍，能import aidl出来
import com.lxh.testaidl.aidl.UST;

aidl实现服务

新增service，命名USTservice

package com.lxh.testaidl;import android.app.IntentService;
import android.content.Intent;
import android.os.IBinder;
import android.os.RemoteException;
import android.util.Log;import androidx.annotation.Nullable;import com.lxh.testaidl.aidl.UST;/*** create by lxh on 2022/12/12 Time：14:35* tip:*/
public class USTservice extends IntentService {private static final String TAG = "USTservice lxh";@Overrideprotected void onHandleIntent(Intent intent) {Log.i(TAG, "onHandleIntent");if (intent != null) {final String action = intent.getAction();}}public TatvUSTservice() {super("USTservice");Log.i(TAG, "USTservice");}public UST.Stub asBinder = new UST.Stub() {@Overridepublic int installPackage(String filepath, int indicator, String version) throws RemoteException {Log.i(TAG, "installPackage(" + filepath + "," + indicator + "," + version);String callerId = getApplicationContext().getPackageManager().getNameForUid(asBinder.getCallingUid());Log.i(TAG, "Calling App:" + callerId);if (callerId.equals("com.lxh.useraidl")) {//在这里放实际的代码}return 1;}};@Overridepublic void onCreate() {super.onCreate();Log.i(TAG, "onCreate");}@Overridepublic int onStartCommand(@Nullable Intent intent, int flags, int startId) {Log.i(TAG, "onStartCommand");return super.onStartCommand(intent, flags, startId);}@Nullable@Overridepublic IBinder onBind(Intent intent) {Log.i(TAG, "onBind");return asBinder;}@Overridepublic boolean onUnbind(Intent intent) {Log.i(TAG, "onUnbind");return true;}@Overridepublic void onDestroy() {Log.i(TAG, "onDestroy");super.onDestroy();}public int installPackage(String filepath, int indicator, String version) {int value = 0;switch (indicator) {case 1:Log.d(TAG, "");value = 1;break;case 2:value = 0;break;default:break;}return value;}
}

打开aidl服务

b新增开机广播接收BootReceiver，用来打开服务

package com.lxh.testaidl;import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.text.TextUtils;
import android.util.Log;/*** create by lxh on 2022/12/12 Time：14:33* tip:*/
public class BootReceiver extends BroadcastReceiver {private static final String TAG = "BootReceiver lxh";@Overridepublic void onReceive(Context context, Intent intent) {Log.i(TAG, "onReceive: " + intent.getAction());if (!TextUtils.isEmpty(intent.getAction()) && intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {Log.i(TAG, "onReceive: ready sent ");Intent it1 = new Intent("com.lxh.testaidl.aidl.UST");it1.setPackage("com.lxh.testaidl");context.startService(it1);}}
}

aidl使用

新建aidl使用工程

新建一个工程。工程名useraidl。包名com.lxh.useraidl。

增加aidl文件

增加aidl文件
