Android静默安装并自动运行

静默安装(需要root权限) :

 /**
     * 执行具体的静默安装逻辑，需要手机ROOT。
     *
     * @param apkPath 要安装的apk文件的路径
     * @return 安装成功返回true，安装失败返回false。

被更新的apk中!:Mainfest中注册广播 :

  <receiver android:name=".receiver.MainReceiver">
            <intent-filter>
                 <action android:name="android.intent.action.PACKAGE_REPLACED" />
                 <data android:scheme="package" />
            </intent-filter>
  </receiver>

 <data android:scheme="package" />这一句很关键!

onReceive方法:

if (intent.getAction().equals(android.intent.action.PACKAGE_REPLACED)) {
            String packageName = intent.getData().getEncodedSchemeSpecificPart();
            if (packageName.equals(PACKAGE_NAME)) {
                LogUtils.e(TAG,"正在重新启动Activity...");
                // 重新启动APP
                Intent intentToStart = context.getPackageManager().getLaunchIntentForPackage(packageName);
                context.startActivity(intentToStart);
            }
        }
