推荐答案

你可以从你的应用程序中通读这段代码

you can read through this code from your application

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()

将此 bufferedReader 存储在字符串或字符串构建器中以检查您的日志

Store this bufferedReader in an string or string builder to check your logs

是的，您需要在清单文件中获得许可:

yes you need permission in your manifest file:

<uses-permission android:name="android.permission.READ_LOGS"/>
