我要提示用户如果未启用该选项。

I want to prompt the user if this option is not enabled.

推荐答案

下面是另一种方式来检查此设置：

Here is another way to check this setting:

boolean isNonPlayAppAllowed = Settings.Secure.getInt(getContentResolver(), Settings.Secure.INSTALL_NON_MARKET_APPS) == 1;

另外这款code，以显示设置用户可能我有用的：

Also this code to show the setting to user might me useful:

if (!isNonPlayAppAllowed) {
    startActivity(new Intent(android.provider.Settings.ACTION_SECURITY_SETTINGS));
}
