推荐答案
/**
* Checks if the device is rooted.
*
* @return <code>true</code> if the device is rooted, <code>false</code> otherwise.
*/
public boolean isRooted() {
// get from build info
String buildTags = android.os.Build.TAGS;
if (buildTags != null && buildTags.contains("test-keys")) {
return true;
}
// check if /system/app/Superuser.apk is present
try {
File file = new File("/system/app/Superuser.apk");
if (file.exists()) {
return true;
}
} catch (Exception exception) {
// ignore
exception.printStackTrace();
}
String[] commands = {
"/system/xbin/which su",
"/system/bin/which su",
"which su"
};
for (String command : commands) {
try {
Runtime.getRuntime().exec(command);
return true;
} catch (Exception exception) {
exception.printStackTrace();
}
}
Log.d("message-startUp: ", "RootUtil");
return false;
}
如果您的设备未root,仍然会出现相同的错误
if your device unrooted, still will bring up the same error
