小编Xco*_*OOB的帖子

我正在尝试为我的项目添加一个库,现在我的当前build.gradle是:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    repositories {
        mavenCentral()
    }

    defaultConfig {
        applicationId "com.example.guycohen.cheaters"
        minSdkVersion 11
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
            // Enabling multidex support.
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
    compile 'com.facebook.android:facebook-android-sdk:4.0.0'
    compile 'com.android.support:multidex:1.0.0'
    compile 'com.parse.bolts:bolts-android:1.+'
    compile 'com.squareup.picasso:picasso:2.5.2'
    compile 'com.whl.handytabbar:library:1.0.4'
    compile 'com.nineoldandroids:library:2.4.0'
    compile 'com.daimajia.easing:library:1.0.1@aar'
    compile 'com.daimajia.androidanimations:library:1.1.3@aar'
}

当我添加一个新库

compile 'com.github.navasmdc:PhoneTutorial:1.+@aar'

我收到此错误:

Error:Execution failed for …

我之前已经看过这个话题,但我认为这不是同一个场景.我正在尝试通过FCM(Firebase云消息传递)向所有其他设备发送来自一台设备(将成为管理设备)的推送通知,而我正准备通过他们的文档.我试图订阅主题或保持简单仍然得到相同的错误,"MissingRegistration".

 String jsonData = "{\"to\":\"/topics/news\",\"notification\":{\"title\":\"title\",\"body\":\"text\" }}";
                byte[] postData = jsonData.getBytes(Charset.forName("UTF-8"));
                int postDataLength = postData.length;

                URL url = new URL("https://fcm.googleapis.com/fcm/send");
                HttpURLConnection con = (HttpURLConnection) url.openConnection();
                con.setDoInput(true);
                con.setDoOutput(true);
                con.setInstanceFollowRedirects(true);
                con.setRequestMethod("POST");

                con.setRequestProperty("Content-Type","application/json");
                con.setRequestProperty("Authorization","key=AIzaSyB70J***-z34q2_h*******qjZsM5zBIf8Y"); //I've added stars :-) 
                con.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
                con.setRequestProperty("Content-Type","charset=UTF-8");
                con.setRequestProperty("Content-Length",Integer.toString(postDataLength));

                con.setUseCaches(false);

                DataOutputStream wr = new DataOutputStream(con.getOutputStream());
                wr.write(postData);

                InputStream inputStream= con.getInputStream();
                BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
                String line = null;
                String outPut = "";
                while (((line = reader.readLine()) != null)){
                    outPut += line;
                }

我的MAC 10.9.1上有最新的Mac OS.最新的Xcode版本5.0.2,现在我已经更新到测试版7.1,但出于某种原因,当我尝试在我的设备上测试应用程序时,我收到此消息:

没有配置的iOS设备可用兼容的iOS版本.将iOS设备与最新版本的iOS连接以运行您的应用程序或选择iOS模拟器作为目标.

因此,在检查时Xcode >> window >> organiser,我注意到我的设备变为橙色而不是绿色并且有此消息:

iOS SDK的此安装不支持"Johnny的iPhone"上的iOS版本.请将设备恢复到下面列出的操作系统版本,或更新到最新版本的iOS SDK; 这是可用的

对此有何解决方案？

我似乎无法找到合适的代码.我想在状态栏下放置20个图像(这将是Y)并将其居中(当然这将是X).我可以轻松地使用故事板来完成它,但我正在努力以编程方式进行.我认为这是我的代码:

var image: UIImage = UIImage(named: "someImage.png")!
            var bgImage = UIImageView(image: image)
            //Tried with self.view.frame.size.height but not working
            bgImage.frame = CGRect(x: 0, y: self.view.frame.size.height - 20, width: self.view.frame.size.width, height: 64)

           //also tried this which not worked as well 
          //  bgImage.center = CGPointMake(self.view.frame.width, self.view.frame.hight - 20)
            self.view.addSubview(bgImage)

我已经搜索了苹果文档,但它很不清楚,任何帮助都会受到赞赏.

我想要实现的应该是非常简单的,但它不起作用.我在我的地图上添加了一个标记,我正试图为它制作一个心跳动画.

我试过以下代码,但没有运气,

   ObjectAnimator pulse = ObjectAnimator.ofPropertyValuesHolder(userLocation,
            PropertyValuesHolder.ofFloat("scaleX",2f),
            PropertyValuesHolder.ofFloat("scaleY",2f)
            );
    pulse.setDuration(310);
    pulse.setRepeatCount(ObjectAnimator.INFINITE);
    pulse.setRepeatMode(ObjectAnimator.REVERSE);
    pulse.start();

任何建议都会很感激,加上使用外部库也可以是一个选项,我刚刚找不到.

好吧,我的RSS应用程序运行完美,现在我正在尝试使用MBProgressHUD添加一些指标.

我在ViewDidLoad下的View Controller中实现了这段代码

 HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view];
[self.navigationController.view addSubview:HUD];
HUD.labelText = @"Loading";

[HUD show:YES];

到现在为止还挺好.该指标正在发挥作用,但当然永远不会消失.我是新手,我试图在实现文件的某些部分添加到我的[HUD隐藏:是]但是它不起作用.如何在数据加载完成后隐藏指示器？这是我的实现文件.

    @implementation ListadoArticulosViewController

- (void)viewDidLoad
{
    [super viewDidLoad];

    // HUD setting 

    HUD = [[MBProgressHUD alloc] initWithView:self.navigationController.view];
    [self.navigationController.view addSubview:HUD];
    HUD.labelText = @"Loading";

    [HUD show:YES];

     NSURL *feedURL = [NSURL URLWithString:@"http://girlsonlyapp.wordpress.com/feed/"];

    feedParser = [[MWFeedParser alloc] initWithFeedURL:feedURL];

    feedParser.delegate = self;

    feedParser.feedParseType = ParseTypeFull;

    feedParser.connectionType = ConnectionTypeAsynchronously;

    listadoArticulos = [[NSMutableArray alloc] init];

    UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];

    [refreshControl addTarget:self action:@selector(cargaArticulos) forControlEvents:UIControlEventValueChanged];
    self.refreshControl = refreshControl;
}

- (void)viewWillAppear:(BOOL)animated {
    [super …

我正在尝试创建一个单一用途的应用程序。因此，我创建了一个BaseActivity，我所有的活动都继承自它。

看起来像

public class LockDeviceActivity extends AppCompatActivity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


    }

    private void startLock() {


        if(mDevicePolicyManager.isLockTaskPermitted(getPackageName())) {
            /**
             * If lock task is permitted, we can lock the task. We can use an external DPM like
             * TestDPC provided by Google to manage lock task list.
             *
             * If the lock is obtained using TestDPC, features like status bar, home button, recent
             * apps, etc is disabled.
             *
