在我的Android Studio项目中有两个build configuration有一些buildConfigField:

    buildTypes {
    def SERVER_URL = "SERVER_URL"
    def APP_VERSION = "APP_VERSION"

    debug {
        buildConfigField "String", SERVER_URL, "http://dev.myserver.com"
        buildConfigField "String", APP_VERSION, "0.0.1"
    }

    release {
        buildConfigField "String", SERVER_URL, "https://myserver.com"
        buildConfigField "String", APP_VERSION, "0.0.1"

        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

我得到的错误如下:

/path/to/generated/BuildConfig.java
    Error:(14, 47) error: ';' expected
    Error:(15, 47) error: ';' expected

生成的BuildCofig.java如下:

public final class BuildConfig {
    public static final boolean DEBUG = Boolean.parseBoolean("true");
    public static final String APPLICATION_ID = "com.mycuteoffice.mcoapp";
    public …

我正在开发一个Android应用程序,它通过REST API与服务器交互.显然,我需要使用不同的URL来开发和发布版本.评论和取消评论代码是非常乏味和错误的.

处理这种情况的最佳方法是哪种？在gradle文件中使用不同的构建类型是可以自动化该过程的类型,但我不确定这是否是正确的方法.

构建类型的数量也有增加的可能性.测试,内部释放等

我知道这有很多问题,但没有一个解决方案适合我,所以这个问题.我想限制用户在今天之前选择日期,但我无法这样做.

public class DatePickerDialogFragment extends DialogFragment {

    private OnDateSetListener listener;

    public void setListener(OnDateSetListener listener) {
        this.listener = listener;
    }

    @NonNull
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Calendar calendar = Calendar.getInstance();
        int year    = calendar.get(Calendar.YEAR);
        int month   = calendar.get(Calendar.MONTH);
        int day     = calendar.get(Calendar.DAY_OF_MONTH);

        DatePickerDialog dialog = new DatePickerDialog(getContext(), listener, year, month, day);
        dialog.getDatePicker().setMinDate(calendar.getTimeInMillis());
        return dialog;
    }
}

我表现为:

DatePickerDialogFragment fragment = new DatePickerDialogFragment();
fragment.setListener(dateSetListener);
fragment.show(getSupportFragmentManager(), "Choose booking date");

我希望用户不应该在今天之前选择日期.正如你所看到的,我setMinDate()用今天的时间调用了方法,但它没有效果.该对话框显示今天之前的日期为灰色但可选择.

我也尝试按照一些stackoverflow答案中的建议进行子类DatePickerDialog和覆盖onDateChanged,但没有任何成功.

我想在测试活动中测试一个片段.我添加TestTragmentActivity到androidTest连同AndroidManifest.xml文件.但是,当我尝试通过ActivityTestRule它使用此活动时,会出现以下错误:

我想将layout xml文件添加到我的androidTest文件夹中,仅用于测试.

我添加了res/layout文件夹androidTest并尝试向其添加布局文件.但它给错误URI is not registered的xmlns:android="http://schemas.android.com/apk/res/android"

不知何故,该项目不会将其识别为有效的布局文件.

我在我们的 android 应用程序中使用Firebase进行远程配置。下面是在我的应用程序类onCreate方法中完成的初始化：

    FirebaseRemoteConfig remoteConfig = FirebaseRemoteConfig.getInstance();
    FirebaseRemoteConfigSettings settings = new FirebaseRemoteConfigSettings.Builder()
                .setDeveloperModeEnabled(BuildConfig.DEBUG)
                .build();
    remoteConfig.setConfigSettings(settings);
    setFirebaseDefault();

    Map<String, Object> defaults = new HashMap<>();
    defaults.put(FirebaseConstantsKt.BREAKING_NEWS, "");
    defaults.put(FirebaseConstantsKt.ENABLE_BREAKING_NEWS, false);
    FirebaseRemoteConfig.getInstance().setDefaults(defaults);
