本文主要是介绍android 7.0 root下静默安装，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
公司产品基于7.0开发，需要实现覆盖升级。之前的产品覆盖升级基于5.1系统，在7.0上不起作用。网上参考了许多博客。最终稀里糊涂的成功了，简单记录。
核心代码只有一句
String command = "pm install -r -i 包名 --user 0 apk路径";execInstallCommand(new String[]{command})
public static final String COMMAND_EXIT = "exit\n";public static final String COMMAND_LINE_END = "\n";public static void execInstallCommand(String[] commands) {Process process = null;BufferedReader successResult = null;BufferedReader errorResult = null;DataOutputStream os = null;try {process = Runtime.getRuntime().exec("su");os = new DataOutputStream(process.getOutputStream());for (String command : commands) {if (command == null) {continue;}// donnot use os.writeBytes(commmand), avoid chinese charset erroros.write(command.getBytes());os.writeBytes(COMMAND_LINE_END);os.flush();}os.writeBytes(COMMAND_EXIT);os.flush(); process.waitFor();} catch (IOException e) {Log.e(TAG,e.getMessage());} catch (Exception e) {Log.e(TAG,e.getMessage());} finally {try {if (os != null) {os.close();}if (successResult != null) {successResult.close();}if (errorResult != null) {errorResult.close();}} catch (IOException e) {Log.e(TAG, "execCommand: ", e);}if (process != null) {process.destroy();}}}
这篇关于android 7.0 root下静默安装的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
