Question

public void uninstallApp(String packageName){
       try {

                String[] command = new String[4];
                command[0] = "su";
                command[1] = "mount -o remount,rw /system";
                command[2] = "rm " + packageName;
                command[3] = "reboot";
                Runtime run = Runtime.getRuntime();
                run.exec(command);

                Log.d("DELETED", packageName);

    } catch (Exception e) {
        // TODO Auto-generated catch block
        Log.e("ERROR ON DELETE", e.getMessage());
    }
}

那是我的代码。此方法接收apk的路径，我需要做的是执行这些命令但不丢失权限。我的意思是，如果我执行＆＃34; su＆＃34;在一个过程中，然后＆＃34; mount＆＃34;在其他过程中。＆＃34;安装＆＃34;没有＆＃34; su＆＃34;访问。所以我需要在一个进程中执行所有这些命令。这不起作用。：\

找到解决方案

StringBuilder cmdReturn = new StringBuilder();

try {
    ProcessBuilder processBuilder = new ProcessBuilder("su","-c mount -o remount,rw /system ; rm " + packageName + " ; reboot");
    Process process = processBuilder.start();

    InputStream inputStream = process.getInputStream();
    int c;
    while ((c = inputStream.read()) != -1) {
        cmdReturn.append((char) c);
    }

    Log.d("CMD RESPONSE", cmdReturn.toString());

} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

您不需要使用ProcessBuilder模式。只需按以下顺序将命令添加到String数组即可：

Process process = Runtime.getRuntime().exec(new String[]{"su", "-c", command1, command2});

需要在Runtime.getRunTime（）。exec上执行多个命令
