如何通过安卓应用发送命令到终端并获取输出?例如,发送“ls /”并将输出打印在GUI中。
你需要使用反射来调用 android.os.Exec.createSubprocess():
public String ls () {
Class<?> execClass = Class.forName("android.os.Exec");
Method createSubprocess = execClass.getMethod("createSubprocess", String.class, String.class, String.class, int[].class);
int[] pid = new int[1];
FileDescriptor fd = (FileDescriptor)createSubprocess.invoke(null, "/system/bin/ls", "/", null, pid);
BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(fd)));
String output = "";
try {
String line;
while ((line = reader.readLine()) != null) {
output += line + "\n";
}
}
catch (IOException e) {}
return output;
}
尝试使用这个答案,它提供了在Android上以编程方式运行shell命令的方法https://dev59.com/pXA75IYBdhLWcg3wVneI#3350332
