Android静默安装并重启APP

一、在AndroidManifest.xml添加权限

二、在AndroidManifest.xml设置程序安装在内存中

    ···

三、下载安装包，执行安装和重启命令

// 安装命令
val installCommand ="LD_LIBRARY_PATH=/vendor/lib*:/system/lib* pm install -r " +"下载后安装包文件的路径，例如：\sd\download\file.apk"
// 重启命令
val restartCommand ="LD_LIBRARY_PATH=/vendor/lib*:/system/lib* am start -n " + packageName + "/" + "启动页的类名称，例如：SplashActivity::class.java.canonicalName"
// 数组
val commands = arrayOf(installCommand, restartCommand)
// 执行命令
val commandResult = ShellUtils.execCmd(commands, true, true)

四、监听安装包替换的广播

public class BootBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals("android.intent.action.PACKAGE_REPLACED")) {
            String packageName = intent.getData().getSchemeSpecificPart();
            if (context.getPackageName().equals(packageName)) {
                // 获取默认启动activity
                Intent launchIntent = context.getPackageManager().getLaunchIntentForPackage(packageName);
                launchIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                context.startActivity(launchIntent);
            }
        }
    }
}

五、注册第四步的广播
