我有两种口味,比如香草和巧克力.我也有Debug和Release构建类型,我需要Vanilla Release才能有一个字段为true,而其他3个组合应该是false.
def BOOLEAN = "boolean"
def VARIABLE = "VARIABLE"
def TRUE = "true"
def FALSE = "false"
VANILLA {
debug {
buildConfigField BOOLEAN, VARIABLE, FALSE
}
release {
buildConfigField BOOLEAN, VARIABLE, TRUE
}
}
CHOCOLATE {
buildConfigField BOOLEAN, VARIABLE, FALSE
}
我有一个错误,所以我猜调试和发布技巧不起作用.有可能这样做吗？
可以通过代码确定设备上当前安装了哪些语言包？试过这个:
Intent detailsIntent = new Intent(RecognizerIntent.ACTION_GET_LANGUAGE_DETAILS);
sendOrderedBroadcast(detailsIntent, null, new LanguageDetailsChecker(), null, Activity.RESULT_OK, null, null);
public class LanguageDetailsChecker extends BroadcastReceiver {
private List<String> supportedLanguages;
@Override
public void onReceive(Context context, Intent intent)
{
Bundle results = getResultExtras(true);
if (results.containsKey(RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES))
{
supportedLanguages =results.getStringArrayList(RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES);
Log.d("TAG","languages: " + supportedLanguages);
}
}
}
但是,输出显示了大量语言,而我只安装了en_UK,en_US和es_ES.任何的想法？
我正在尝试检查是否有蓝牙耳机连接到设备
BluetoothAdapter mAdapter;
mAdapter = BluetoothAdapter.getDefaultAdapter();
Log.d("TAG","HEADSET: " + mAdapter.getProfileConnectionState(BluetoothProfile.HEADSET));
Log.d("TAG","HEALTH: " + mAdapter.getProfileConnectionState(BluetoothProfile.HEALTH));
Log.d("TAG","A2DP: " + mAdapter.getProfileConnectionState(BluetoothProfile.A2DP));
这始终返回 HEADSET 2（已连接）、Health 0（已断开连接）和 A2DP 0（已断开连接）。我是否连接了蓝牙耳机并不重要，只有在禁用蓝牙时，耳机连接状态才为 0

我有一个包含大量活动的应用程序,以及Flurry分析API密钥.我希望一场激烈的会议成为一个整个会议,而人们建议在每个活动中开始和停止会话.但是,这将导致50次会议/真实会话.
我将onStartSession()方法放在登录活动上,并在登出时放入onStop.我记录的事件遇到了一些麻烦,看起来它正在跳过它们.
有什么想法吗？
我想使用android内部类com.android.internal.widget.LockPatternUtils.
我搜索了一些例子,我得到了这个:
LockPatternUtils lpu = new LockPatternUtils(this.getContentResolver());
但是,我无法导入,autimport不会出现并手动执行
import com.android.internal.widget.LockPatternUtils
不起作用.
这是怎么处理的？我认为有一些关于创建界面但不确定它的东西
编辑:我得到了这个:
boolean patternLocked = android.provider.Settings.System.getInt(
getContentResolver(),Settings.System.LOCK_PATTERN_ENABLED, 0)==1;
这适用于模式锁定,但我不知道引脚或密码锁定
