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 30
buildToolsVersion "30.0.2"
defaultConfig {
applicationId "com.lxh.testaidl"
minSdkVersion 28
targetSdkVersion 30
versionCode 1
def date = new Date().format("yyyyMMddHHmm" , TimeZone.getTimeZone("GMT+08"))
versionName "testaidl-V1.0-"+date
testInstrumentationRunner "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 true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
signingConfig signingConfigs.release
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility 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";
@Override
protected 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() {
@Override
public 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;
}
};
@Override
public void onCreate() {
super.onCreate();
Log.i(TAG, "onCreate");
}
@Override
public int onStartCommand(@Nullable Intent intent, int flags, int startId) {
Log.i(TAG, "onStartCommand");
return super.onStartCommand(intent, flags, startId);
}
@Nullable
@Override
public IBinder onBind(Intent intent) {
Log.i(TAG, "onBind");
return asBinder;
}
@Override
public boolean onUnbind(Intent intent) {
Log.i(TAG, "onUnbind");
return true;
}
@Override
public 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;
/**

public class BootReceiver extends BroadcastReceiver {
private static final String TAG = "BootReceiver lxh";
@Override
public 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);
}
}
}
