在 Android ICS 中，我们可以禁用内置应用程序。是否可以知道特定应用程序是否在代码中被禁用或启用？

ApplicationInfo ai = getActivity().getPackageManager().getApplicationInfo("your_package",0);
                    
boolean appStatus = ai.enabled;

如果appStatus是，false则应用程序被禁用:)

编辑：

在 Android 11（API 级别 30）上，您还需要告诉清单您要从哪些应用收集信息：

<manifest package="com.example.game">
    <queries>
        <package android:name="com.example.store" />
    </queries>
</manifest>

接受的答案也可能导致异常，即，NameNotFoundException因此您可能必须构建一个静默捕获异常并确定启用状态的流程（它实际上是第三种状态，即未安装）。

因此，最好像这样找到已启用和已安装的状态：

public static final int ENABLED = 0x00;
    public static final int DISABLED = 0x01;
    public static final int NOT_INSTALLED = 0x03;

    /**
     * @param context Context
     * @param packageName The Package name of the concerned App
     * @return State of the Application.
     *
     */
    public static int getAppState(@NonNull Context context, @NonNull String packageName) {
        final PackageManager packageManager = context.getPackageManager();

        // Check if the App is installed or not first
        Intent intent = packageManager.getLaunchIntentForPackage(packageName);
        if (intent == null) {
            return NOT_INSTALLED;
        }
        List<ResolveInfo> list = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
        if(list.isEmpty()){
            // App is not installed
            return NOT_INSTALLED;
        }
        else{
            // Check if the App is enabled/disabled
            int appEnabledSetting = packageManager.getApplicationEnabledSetting(packageName);
            if(appEnabledSetting == COMPONENT_ENABLED_STATE_DISABLED || 
                    appEnabledSetting == COMPONENT_ENABLED_STATE_DISABLED_USER){
                return DISABLED;
            }
            else{
                return ENABLED;
            }
        }
    }

尝试http://developer.android.com/reference/android/content/pm/PackageManager.html#getApplicationInfo%28java.lang.String,%20int%29并检查返回的 ApplicationInfo 对象中的“启用”标志。
