我正在尝试以编程方式执行adb命令
这是我的代码:
File f = new File(Environment.getExternalStorageDirectory(), "screen" + System.currentTimeMillis() + ".png");
new ExecuteCommand(MainActivity.this).execute("adb shell screencap -p "
+ Environment.getExternalStorageDirectory().getPath() +
"/" + "screen" + System.currentTimeMillis() + ".png");
ExecuteCommand Class:
public class ExecuteCommand extends AsyncTask<String, String, String> {
Context mContext=null;
public ExecuteCommand(Context _ctx)
{
mContext =_ctx;
}
ProgressDialog progressdailog;
@Override
protected void onPreExecute() {
super.onPreExecute();
progressdailog = ProgressDialog.show(mContext,
"Executing", "Please Wait");
}
@Override
protected String doInBackground(String... params) {
Process p;
StringBuffer output = new StringBuffer();
try {
p = Runtime.getRuntime().exec(params[0]);
BufferedReader reader = new BufferedReader(
new InputStreamReader(p.getInputStream()));
String line = "";
while ((line = reader.readLine()) != null) {
output.append(line + "\n");
p.waitFor();
}
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
String response = output.toString();
return response;
}
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
progressdailog.dismiss();
Log.e("Output", result);
}
}
日志中的问题:
07-31 15:26:31.832 18716-18716 / com.example E / Output:无法绑定'tcp:5038'*守护程序未运行。现在从端口5038开始*
我无法截取屏幕截图,但如果我在命令提示符下运行相同的命令,那么这很正常。
但是如果我执行
new ExecuteCommand(MainActivity.this).execute("ls");
这很好用。命令中的问题在哪里?
答案 0 :(得分:5)
adb shell
。但是当您在设备上执行命令时,您不需要adb shell
这将是干净的:
new ExecuteCommand(MainActivity.this).execute("screencap -p " + f);
