我需要将整个Logcat写入sdcard而不是筛选后的Logcat。因此,我尝试了以下方法:
String[] cmd ={"/system/bin/logcat " +"-f"+" /sdcard/d.txt"};
Log.d("NTK","cmd string"+cmd);
Runtime run = Runtime.getRuntime();
Process pr;
try {
pr = run.exec(cmd);
pr.waitFor();
BufferedReader buf = new BufferedReader(new InputStreamReader(pr.getInputStream()));
String line = "";
while ((line=buf.readLine())!=null) {
System.out.println(line);
Log.i(NTL, "lines"+line);
}
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
我已经在清单文件中授予了所有权限。
无法将logcat写入sd卡。
