Android 获取当前 运行 应用程序包名称
Android get current running application package name
我有以下代码 运行 在 Android 5.0 和 6.0 中正确，但如果我将此应用程序用于 Android 4.4 设备，则应用程序会崩溃。请帮我解决这个问题。
下面是我的代码
if (Build.VERSION.SDK_INT > 20) {
packageName = mActivityManager.getRunningAppProcesses().get(1).processName;
} else {
packageName = mActivityManager.getRunningTasks(1).get(0).topActivity.getPackageName();
}
Log.e("Package : ", "" + packageName);
显示错误，

您可以使用
getApplicationContext().getPackageName();
