MTK-Android13-包安装器PackageInstaller 静默安装实现

目的

• 我们最终是为了搞明白安装的整个流程。一方面通过安卓系统自带的包安装器来了解PMS 安装流程；另一方面熟悉框架层Framework 针对Android apk 安装流程。

前两篇文章分析了PackagerInstaller 安装流程。 Android13-包安装器PackageInstaller-之apk安装跳转
Android13-包安装器PackageInstaller-之apk安装流程
后面空了再分析框架层PMS的处理以及在框架层面的少许拦截和加功能。

• 实现需求定制：静默安装-安装界面定制-安装拦截验证。【核心目的】

安装流程和PMS了解不用多说了; 安装定制相关：
如

• 手机上安装时候弹出锁屏界面需要输入密码;
• 安装时候弹出密码框，让用户输入定制的特殊密码功能；
• 安装页面客制化需求

安装方式

当然正常的安装分为类型我其实理解为大概3种

• 无界面安装：PMS启动阶段 比如系统第一次启动，所有内置app自动批量安装；我们重试系统app开发时候，或者内置系统apk开发时候，删除对应的目录下的apk和apk对应的/data/分区下的apk所有安装信息后，push
  更新的apk到系统，重启。 apk 自动重新安装。

• adb 安装： adb 命令安装，通过adb install 安装，依托守护进程来实现安装

• 点击安装或者调用方法安装：应用市场再下载完apk后自动进入进入包管理器进行安装；sd开或者外部存储中的安装包点击安装自动进入包管理器进行安装

静默安装实现

修改文件

添加文件：

frameworks/base/packages/PackageInstaller/src/com/android/packageinstaller/SilenceInstallReceiver.java
frameworks/base/packages/PackageInstaller/src/com/android/packageinstaller/SilenceInstallManager.java

修改文件：

frameworks/base/packages/PackageInstaller/src/com/android/packageinstaller/UninstallerActivity.java frameworks/base/packages/PackageInstaller/src/com/android/packageinstaller/PackageInstallerApplication.java
frameworks/base/packages/PackageInstaller/src/com/android/packageinstaller/InstallStart.java
frameworks/base/packages/PackageInstaller/AndroidManifest.xml
frameworks/base/services/core/java/com/android/server/wm/ActivityStarter.java

实现思路

按照前两篇PackageInstaller 包管理器 了解的安装流程和思路，实现方案总结以下两点：

• 延用现有的所有PackagerInstaller 逻辑，在判断安装地方 一路静默，默认同意。【弊端 涉及到多个Activity，特别是安装流程，等待都是花时间的，造成界面App假死】
• 将所有的安装逻辑放到第一个InstallStart Activity里面，对Activity实现，在Activity 里面进行异步处理，同时对Activity进行返回后台。 【不要影响界面上面正在操作的App】
• 在跳转到InstallStart Activity后，跳转到Service 里面处理，结束当前Activity 即可，这样安装逻辑就在Service 里面了。

实现具体方案

这里列举在 InstallStart Activity 里面进行逻辑处理，作为一个方案的引入。 实际项目中直接在Service里面处理的。

SilenceInstallReceiver

新增的一个安装成功监听、通知显示提示，根据自身需要是否需要，进行定制或直接删除。

public class PackageInstalledReceiver extends BroadcastReceiver {
    private static final String TAG = PackageInstalledReceiver.class.getSimpleName();

    private static final boolean DEBUG = false;

    @Override
    public void onReceive(Context context, Intent intent) {
        if (Settings.Global.getInt(context.getContentResolver(),
                Settings.Global.SHOW_NEW_APP_INSTALLED_NOTIFICATION_ENABLED, 0) == 0) {
            return;
        }

        String action = intent.getAction();

        if (DEBUG) {
            Log.i(TAG, "Received action: " + action);
        }

        if (Intent.ACTION_PACKAGE_ADDED.equals(action)) {
            Uri packageUri = intent.getData();
            if (packageUri == null) {
                return;
            }

            String packageName = packageUri.getSchemeSpecificPart();
            if (packageName == null) {
                Log.e(TAG, "No package name");
                return;
            }

            if (intent.getBooleanExtra(Intent.EXTRA_REPLACING, false)) {
                if (DEBUG) {
                    Log.i(TAG, "Not new app, skip it: " + packageName);
                }
                return;
            }

            // TODO: Make sure the installer information here is accurate
            String installer =
                    context.getPackageManager().getInstallerPackageName(packageName);
            new PackageInstalledNotificationUtils(context, installer,
                    packageName).postAppInstalledNotification();
        }
    }
}	
   

SilenceInstallManager

静默安装的核心工具类，做了以下几个工作，针对PackageInstall 安装流程进行了一个提取

• copy 文件,安装包文件拷贝
• session 的创建、注册回调、交互，安装工作提交到Framework层 commit 、registerSessionCallback(mSessionCallback)
• 这里封装了静默安装和卸载的方法

PackageInstallerApplication.java

Application 中初始化工具类
	SilenceInstallManager.getInstance(this);

UninstallerActivity.java

静默卸载方案实现，调用工具类方法

 onCreate 方法中 
 if (intent.getBooleanExtra(SilenceInstallReceiver.SILENCE_INSTALL_KEY, false)) {
			 Log.d(TAG, "silenceUninstall ....");
            SilenceInstallManager.getInstance(this).silenceUninstall(mPackageName);
            return;
 }
	

InstallStart

内部创建一个异步线程

   // 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;
        }

异步线程作什么呢？

• 拷贝文件
• 创建uri,发送广播 通知

@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(LOG_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(LOG_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(LOG_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(LOG_TAG, "send to install");
            } else {
                Log.d(LOG_TAG, "copy file from user app fail");
            }

            finish();
        }
    }  
   

测试验证

这里写了一个简单的方法，直接验证功能

 private fun installTest() {
        // val appPath ="/sdcard/aiqiyi.apk"       // getExternalFilesDir(null)!!.absolutePath + File.separator + "aiqiyi.apk"
        //val appPath =getExternalFilesDir(null)!!.absolutePath + File.separator + "aiqiyi.apk"
       // val appPath ="/data/data/com.deling.launcher/files" + File.separator + "aiqiyi.apk"
        val aPath ="/data/data/com.deling.launcher/files" + File.separator + "aiqiyi.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
        }


        //大于7.0使用此方法
        val apkUri = FileProvider.getUriForFile(
            ContextProvider.get().context,
            "com.deling.launcher.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)
            //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)
            }
        }
    }

分析：
这里写了传递了三个参数

• silence_install 是否静默安装
• is_launch 安装成功后是否启动起来
• 是否允许在后台运行，这样保证不影响实际界面显示使用

测试结果跳转到了这个界面，说明所有流程都是走通了的，功能可行：

实践中遇到的问题

• 不同ODM厂商Android源码、相同ODM厂商Android 不同Android版本，源码少许不一致，需要自己更具实际情况适配 改一改。涉及到方法名、包括类名。
• 针对GMS版本产品，谷歌的安装包程序会GooglePackageInstaller 覆盖源码里面PackageInstaller 程序，实际测试就会发现安装程序走的居然是包名为com.google.android.packageinstaller的程序。
  但是谷歌安装包程序提供的是apk 形式，路径如下： \vendor\google\apps\GooglePackageInstaller\GooglePackageInstaller.apk 不是源码形式是无法更改的。那又怎么实现呢？
  可以尝试把安装逻辑代码放到系统设置里面去，跳转入口直接跳转到设置。【针对定制的安装apk程序，如果GMS认证能过的情况下】
