前言
在RK 平台 Android15 上面做静默安装功能
一、 需求
在Android15 上面实现静默安装功能，不要用脚本实现，借助包安装器PackageInstaller 来实现。
二、参考资料
MTK-Android13-包安装器PackageInstaller 静默安装实现
本文笔记完全参考之前知识点 MTK平台Android13 版本思想，在安装器App-PackageInstaller 基础上更改部分流程实现静默安装功能。
- 可以参考、copy 全部代码：思想完全一样的，借助安装器，添加自己的业务代码，客户是否静默安装看客户自己选择。
- 以前是Android13 且 MTK平台，在Android15 上面部分API、机制、权限有区别，适当几个点适配下即可，本章会后面分析会做简单介绍。

三、文件修改
包安装前 PackageInstaller 目录：/frameworks/base/packages/PackageInstaller
新增文件：
java
src/com/android/packageinstaller/SilenceInstallManager.java
src/com/android/packageinstaller/SilenceInstallReceiver.java修改文件：
java
AndroidManifest.xml
src/com/android/packageinstaller/InstallStart.java
src/com/android/packageinstaller/PackageInstallerApplication.java
src/com/android/packageinstaller/UninstallerActivity.java
四、实现方案
1、InstallStart - onCreate 方法中-判断是否拦截进行静默安装-拷贝文件
在 InstallStart 入口onCreate 方法中，拦截，是否进行静默安装，如果是，那么就进行静默安装逻辑，拷贝文件。拦截正常的安装流程。
java
// modify by fangchen start
// if silence install ->to silence install
if (intent.getBooleanExtra(SilenceInstallReceiver.SILENCE_INSTALL_KEY, false)) {
Log.d(TAG," StagingAsyncAppTask to execute ");
StagingAsyncAppTask mStagingTask = new StagingAsyncAppTask(intent.getBooleanExtra(SilenceInstallReceiver.IS_LAUNCH_KEY, false));
mStagingTask.execute(getIntent().getData());
return;
}
// modify by fangchen end拷贝 文件资源代码如下：
java
@SuppressLint("NewApi")
private final class StagingAsyncAppTask extends AsyncTask<Uri, Void, File> {
private boolean mIsLaunch;
public StagingAsyncAppTask(boolean isLaunch){
mIsLaunch = isLaunch;
}
@Override
protected File doInBackground(Uri... params) {
Log.d(TAG, "===========copy file from user app start");
if (params == null || params.length <= 0) {
return null;
}
Uri packageUri = params[0];
try (InputStream in = getContentResolver().openInputStream(packageUri)) {
// Despite the comments in ContentResolver#openInputStream the returned stream can
// be null.
if (in == null) {
return null;
}
File mStagedFile = TemporaryFileManager.getStagedFile(InstallStart.this);
try (OutputStream out = new FileOutputStream(mStagedFile)) {
byte[] buffer = new byte[1024 * 1024];
int bytesRead;
while ((bytesRead = in.read(buffer)) >= 0) {
// Be nice and respond to a cancellation
out.write(buffer, 0, bytesRead);
}
}
return mStagedFile;
} catch (IOException | SecurityException | IllegalStateException e) {
Log.w(TAG, "Error staging apk from content URI", e);
}
return null;
}
@Override
protected void onPostExecute(File installFile) {
if (null != installFile) {
// Now start the installation again from a file
Log.d(TAG, "copy file from user app finish");
Intent installIntent = new Intent(SilenceInstallReceiver.SILENCE_INSTALL_APP);
installIntent.putExtra(SilenceInstallReceiver.APP_URI_KEY, Uri.fromFile(installFile));
installIntent.putExtra(SilenceInstallReceiver.IS_LAUNCH_KEY, mIsLaunch);
installIntent.addFlags(Intent.FLAG_RECEIVER_INCLUDE_BACKGROUND);
installIntent.setPackage("com.android.packageinstaller");
sendBroadcast(installIntent);
Log.d(TAG, "send to install");
} else {
Log.d(TAG, "copy file from user app fail");
}
finish();
}
}2、SilenceInstallReceiver 接收静默安装广播请求-进行静默安装业务
如上，在进行安装初期InstallStart 中 判断当前进行静默后，广播开始通知进行静默安装
java
package com.android.packageinstaller;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.util.Log;
public class SilenceInstallReceiver extends BroadcastReceiver {
public static final String SILENCE_INSTALL_APP = "com.android.packageinstaller.ACTION_SILENCE_INSTALL";
public static final String SILENCE_INSTALL_KEY = "silence_install";
public static final String IS_LAUNCH_KEY = "is_launch";
public static final String APP_URI_KEY = "app_uri";
private static final String TAG = "SilenceInstallReceiver";
@Override
public void onReceive(Context context, Intent intent) {
Log.w(TAG, "SilenceInstallReceiver getAction---->" + intent.getAction());
if (SILENCE_INSTALL_APP.equals(intent.getAction())) {
Uri uri = intent.getParcelableExtra(APP_URI_KEY);
boolean isLaunch = intent.getBooleanExtra(IS_LAUNCH_KEY, false);
SilenceInstallManager.getInstance(context).silenceInstall(uri, isLaunch);
}
}
}3、静默安装核心工具类-SilenceInstallManager
假使对安装流程有相关的了解和掌握，我个人经验就是两点：
- 文件的拷贝，
uri的传递，按照规范传递参数拼凑数据 - 进行
Session处理，提交 到Framework层 进行安装。 - 对于安装回调进度，注册
Session回调而已

}4、PackageInstallerApplication 初始化静默安装工具
java
SilenceInstallManager.getInstance(this);
5、AndroidManifest 配置 广播组件
java
<!-- modify by fangchen start -->
<receiver android:name=".SilenceInstallReceiver"
android:exported="true">
<intent-filter android:priority="1">
<action android:name="com.android.packageinstaller.ACTION_SILENCE_INSTALL" />
</intent-filter>
</receiver>
<!-- modify by fangchen end -->五、实验验证-进行静默安装测试
这里可以传递两个参数：
- 是否静默安装
silence_install，如果否 则走默认的安装器安装方式 - 安装成功后是否自启动
is_launch
备注说明：在实际业务中，如果下载成功 软件包 文件 apk,后直接调用当前业务代码即可实现。
java
val aPath ="/data/data/com.fish.togetsn/files" + File.separator + "bilibili.apk"
Log.d(TAG," aPath path:"+aPath);
val appFile = File(aPath)
if (!appFile.exists()) {
//showToast("请在" + getExternalFilesDir(null)!!.absolutePath + File.separator + "目录中放置升级文件")
ToastUtils.showShort("请 配置文件")
return@setOnClickListener
}
//大于7.0使用此方法
val apkUri = FileProvider.getUriForFile(
ContextProvider.get().context,
"com.fish.togetsn.fileProvider",
appFile
)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val installApkIntent = Intent()
installApkIntent.setAction(Intent.ACTION_VIEW)
installApkIntent.addCategory(Intent.CATEGORY_DEFAULT)
installApkIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
installApkIntent.setDataAndType(apkUri, "application/vnd.android.package-archive")
installApkIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
//设置静默安装标识
installApkIntent.putExtra("silence_install", true)
installApkIntent.setPackage("com.android.packageinstaller")
//设置安装完成是否启动标识
installApkIntent.putExtra("is_launch", true)
//设置后台中启动activity标识
// installApkIntent.putExtra("allowed_Background", true)
if (packageManager.queryIntentActivities(installApkIntent, 0).size > 0) {
startActivity(installApkIntent)
}
}六、拓展思路-讨论
- 这里模仿的是下载软件成功后，借用 系统自带安装前
PackageInstaller实现。 其中拷贝文件是在入口InstallStart这个Activity中实现的，那么实际上 我自己把这部分代码实现，也就是拷贝文件实现，直接发送广播给安装器进行安装业务不行吗？ - 如上 思考，我们使用了
PackageInstaller的入口InstallStart这个Activity，屏幕会闪一下，实际过程中这个如果避免达到无感？ - 这里都是在借助
PackageInstaller这个包实现的，比如我们设置com.android.packageinstaller指定的包名进行application/vnd.android.package-archive业务，实际上 静默安装和非静默安装混在一起的， 那么就不能分离开来直接在Framework层的Service服务中实现吗？ 这里先给出答案，绝对可行。 - 其实静默安装 不管哪一个版本都有自己的一套，比如开机第一次 会内置apk， 把这个业务流程单独提出来不也是一个思路吗。
总结
- 这里进行了Android15 ，RK平台 静默安装功能，针对以前的知识点再次实践而已，这里面涉及到一些API变化、规则变化，参考
PackageInstaller业务代码和流程实现。 - 静默安装核心要点还是
session的传递、提交、校验 等。 分为两部分：前端和Framework层，每个知识点都很重要，建议多研究代码，会收获很多。
