String buffer="";

while((buffer=bufferedReader.readLine())!=null)

    //fileobj.write(buffer);
    System.out.println(buffer);

You can provide DUMP permission from adb

adb shell pm grant <your-package-name> android.permission.DUMP

There are two other ways you can use to get cpu information

  1. use top command int adb shell, get most information

    top -n 1

  2. You also can cat information in /proc/stat and /proc/pid/stat to get the cpu information

    cat /proc/stat

    If you wanna details, check Get Memeory Usage

The android dev team decided to stop granting these permissions to third-party apps. Only system apps can now get them.

You can access some memory information by checking /proc/meminfo file, there is also other intersting files under /proc/. Hopefully these files will be readable in future releases

Code example to fetch meminfo:

    public static String showMemInfo() {
    StringBuilder meminfo = new StringBuilder();
    try {
        ArrayList<String> commandLine = new ArrayList<String>();
        commandLine.add("cat");
        commandLine.add("/proc/meminfo");

        Process process = Runtime.getRuntime().exec(commandLine.toArray(new String[commandLine.size()]));
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));

        String line;
        while ((line = bufferedReader.readLine()) != null) {
            meminfo.append(line);
            meminfo.append("\n");
        }

    } catch (IOException e) {
        Log.e(LOG_TAG, "Could not read /proc/meminfo", e);
    }

    return meminfo.toString();
}

PS: I know it's not verbose like dumpsys ;)

The DUMP permission is defined as android:protectionLevel="signatureOrSystem" so you can't get it unless your app is signed with the platform key, or installed in the system partition.
