确定一个根深蒂固的设备上运行 [英] Determine if running on a rooted device

问题描述

我的应用程序具有一定的一项功能，将只能工作在设备上，其中根可用。而不是当它被使用（并显示相应的错误信息给用户），此功能失败了，我会preFER的能力默默地检查根可用首先，如果没有，躲在各自的选项位居第一。

My app has a certain piece of functionality that will only work on a device where root is available. Rather than having this feature fail when it is used (and then show an appropriate error message to the user), I'd prefer an ability to silently check if root is available first, and if not,hide the respective options in the first place.

有没有办法做到这一点？

Is there a way to do this?

推荐答案

下面是一个类，将检查根三种方式之一。

Here is a class that will check for Root one of three ways.

/** @author Kevin Kowalewski */
public class RootUtil {
    public static boolean isDeviceRooted() {
        return checkRootMethod1() || checkRootMethod2() || checkRootMethod3();
    }

    private static boolean checkRootMethod1() {
        String buildTags = android.os.Build.TAGS;
        return buildTags != null && buildTags.contains("test-keys");
    }

    private static boolean checkRootMethod2() {
        String[] paths = { "/system/app/Superuser.apk", "/sbin/su", "/system/bin/su", "/system/xbin/su", "/data/local/xbin/su", "/data/local/bin/su", "/system/sd/xbin/su",
                "/system/bin/failsafe/su", "/data/local/su" };
        for (String path : paths) {
            if (new File(path).exists()) return true;
        }
        return false;
    }

    private static boolean checkRootMethod3() {
        Process process = null;
        try {
            process = Runtime.getRuntime().exec(new String[] { "/system/xbin/which", "su" });
            BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));
            if (in.readLine() != null) return true;
            return false;
        } catch (Throwable t) {
            return false;
        } finally {
            if (process != null) process.destroy();
        }
    }
}
