Do I need a super user permission? 我需要超级用户权限吗?
you can read through this code from your application 您可以从应用程序中阅读此代码
ArrayList<String> commandLine = new ArrayList<String>();
commandLine.add("logcat"); //$NON-NLS-1$
commandLine.add("-d"); //$NON-NLS-1$
ArrayList<String> arguments =
((params != null) && (params.length > 0)) ? params[0] : null;
if (null != arguments) {
commandLine.addAll(arguments);
}
Process process = Runtime.getRuntime().exec(commandLine.toArray(new String[0]));
BufferedReader bufferedReader = new BufferedReader(
new InputStreamReader(process.getInputStream()), 1024);
bufferedReader.readLine()
Store this bufferedReader in an string or string builder to check your logs 将此bufferedReader存储在字符串或字符串生成器中以检查日志
yes you need permission in your manifest file: 是的,您需要在清单文件中获得权限:
<uses-permission android:name="android.permission.READ_LOGS"/>
