Android系统实现静默安装源码

Android系统 实现静默安装

Android实现静默安装需要用到一些隐藏的api接口&＃xff0c;第三方apk无法直接调用其接口。所以实现这个功能需要编写到然后去系统中编译生成apk。这里记录下自己实现的静默安装功能的代码。

主要代码&＃xff1a;public class InstallPackageActivity extends AppCompatActivity {private String APK_NAME &＃61; "TencentVideo.apk";private String mAutoStartPackageName;private int INSTALL_COMPLETE &＃61; 1;private Button click;private Context mContext &＃61; InstallPackageActivity.this;private Handler mHandler &＃61; new Handler() {&＃64;Overridepublic void handleMessage(Message msg) {super.handleMessage(msg);if (msg.what &＃61;&＃61; 1) {if (msg.arg1 &＃61;&＃61; 1) {Toast.makeText(getApplicationContext(), "安装成功", Toast.LENGTH_SHORT).show();Log.i("liu", "Installation success!");changeButtonState(true);} else {Toast.makeText(getApplicationContext(), "安装失败", Toast.LENGTH_SHORT).show();Log.i("liu", "Installation failure!");click.setEnabled(true);click.setText(mContext.getResources().getString(R.string.button_silent_install_app_fail));}}}};&＃64;Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_install_package);click &＃61; (Button) this.findViewById(R.id.click);click.setOnClickListener(new View.OnClickListener() {&＃64;Overridepublic void onClick(View v) {installApp();changeButtonState(false);}});}private void installApp() {String fileName &＃61; Environment.getExternalStorageDirectory() &＃43; "/" &＃43; APK_NAME;if (!new File(fileName).exists()) {Log.e("liu", "file name is not exists!");return;}String packageName;int installFlags &＃61; 0;Uri uri &＃61; Uri.fromFile(new File(fileName));PackageManager pm &＃61; getPackageManager();PackageInfo info &＃61; pm.getPackageArchiveInfo(fileName, PackageManager.GET_ACTIVITIES);if (info !&＃61; null) {packageName &＃61; info.applicationInfo.packageName;Log.i("liu", "packageName -> " &＃43; packageName);try {PackageInfo packageInfo &＃61; pm.getPackageInfo(packageName, PackageManager.GET_UNINSTALLED_PACKAGES);Log.i("liu", "packageInfo -> " &＃43; packageInfo);if (packageInfo !&＃61; null) {installFlags |&＃61; PackageManager.INSTALL_REPLACE_EXISTING;}} catch (PackageManager.NameNotFoundException e) {e.printStackTrace();}mAutoStartPackageName &＃61; packageName;PackageInstallObserver observer &＃61; new PackageInstallObserver();pm.installPackage(uri, observer, installFlags, mAutoStartPackageName);}}private void changeButtonState(boolean isEnable) {click.setEnabled(isEnable);if (isEnable) {click.setText(mContext.getResources().getString(R.string.button_silent_install_app_complete));} else {click.setText(mContext.getResources().getString(R.string.button_silent_installing_app));}}class PackageInstallObserver extends IPackageInstallObserver.Stub {public void packageInstalled(String packageName, int returnCode) {Log.i("liu", "send message to main thread!");Message msg &＃61; mHandler.obtainMessage(INSTALL_COMPLETE);msg.arg1 &＃61; returnCode;mHandler.sendMessage(msg);}}
}


上面的代码看情况复制进去即可使用&＃xff0c;主要的安装在installApp&＃xff08;&＃xff09;方法中&＃xff0c;安装完成之后会调用packageInstalled方法&＃xff0c;returnCode返回1表示安装成功。

添加权限

需要添加如下权限

编写Android.mk文件

上面的代码编写完成之后&＃xff0c;在系统中编译还需要编写Android.mk文件。

最终的代码结构如图

把当前整个工程放到源码的package/app目录下&＃xff0c;然后cd android/package/app/SlientInstall目录&＃xff0c;然后mm即可编译成apk&＃xff0c;目前我只在6.0&＃xff0c;7.1&＃xff0c;8.1的系统上尝试过。
