我正在使用Facebook Audience Network并根据这篇文章

我没有缓存广告,但广告在屏幕上停留而没有刷新.我正在加载所有广告,他们会一直在屏幕上,直到用户关闭应用.

private void initializeAds() {
        //ENABLE TESTING MODE
        if (BuildConfig.DEBUG) {
            AdSettings.addTestDevice("alksdfj");//For testing ads
        }

        //NATIVE AD
        nativeAd = new NativeAd(this, "alksdjf");
        nativeAd.setAdListener(new AdListener() {

            @Override
            public void onError(Ad ad, AdError adError) {

            }

            @Override
            public void onAdLoaded(Ad ad) {
                // Render the Native Ad Template
                View adView = NativeAdView.render(MainActivity.this, nativeAd, NativeAdView.Type.HEIGHT_120);
                LinearLayout nativeAdContainer = (LinearLayout) findViewById(R.id.native_ad_container);
                // Add the Native Ad View to your ad container
                nativeAdContainer.addView(adView);
            }

            @Override
            public void onAdClicked(Ad ad) {

            } …

I am trying to add Firebase crashlytics to an existing project (not developed by me). I keep getting the error

ERROR: Could not find com.google.gms.google-services:4.2.0:.
Required by:
    project :
Search in build.gradle files

I have gone through all (or most ) of the solution that asks to add maven { url 'https://maven.google.com' } and none of them work. I am getting the above error for all the solution.

Please not other projects that i have developed are working …

我需要获取android锁屏活动的包名.我用google搜索除了/sf/answers/1181674511/之外什么都没找到,这似乎不起作用.

有没有办法获得锁屏包名称

我正在尝试在我的应用中放置广告.根据Admob 文档,我必须初始化移动广告SDK

MobileAds.initialize(this, "YOUR_ADMOB_APP_ID");

这会导致代码中高ram使用率的飙升.

但是,如果我删除此行,则ram使用率下降&且这行代码似乎对应用内部的服务器广告没有任何影响.

此外,当从admob ram使用请求广告再次飙升并在应用启动时导致3-4个GC事件.我相信这是内存泄漏.

这是我在onCreate方法中请求广告的方式

AdRequest request = null;
        if (BuildConfig.DEBUG) {
            //Facebook Audience Network
            List<String> testDeviceId = new ArrayList<>();
            testDeviceId.add("TESTID");//Redmi Note 3
            testDeviceId.add("TESTID");//Moto G 1st Gen

            AdSettings.addTestDevices(testDeviceId);

            //Google Ad-mob
            request = new AdRequest.Builder()
                    .addTestDevice("TESTID")//Redmi Note 3
                    .addTestDevice("TESTID")//Mot G 1st Gen
                    .build();
        } else {
            request = new AdRequest.Builder()
                    .build();
        }

        AdView mAdView = findViewById(R.id.adView);
        mAdView.loadAd(request);

加载此横幅广告时,会启动多个GC事件.如果我不加载广告,则GC事件永远不会被踢入.

这种行为与admob一样正常吗？我该如何解决这个问题？

我有一个画布,我试图通过JavaScript获得高度,但它返回半高,然后返回实际高度

这是我正在使用的简单代码

var canvas = document.getElementById("clock");
var context = canvas.getContext("2d");

document.getElementById("status").innerHTML = canvas.height;
console.log(canvas.height);

canvas#clock{
	width:300px;
	height:300px;
	border:#D50003 1px solid;
	background:#1E1E1E;
}

<canvas id="clock"></canvas>
<div id="status"></div>

我正在使用OkHttp库来进行多部分数据,一切都很好我没有任何错误但是当我编译程序时它会给我错误

错误:(172,40)错误:无法访问未找到okio.ByteString的ByteString类文件

这里发生错误 RequestBody.create(MEDIA_TYPE_JPG, new File(data.getFileParam())))

这是实现多部分请求的整个方法代码

public static String makeRequest(RequestConstructor data, String a, String b) {
    final MediaType MEDIA_TYPE_JPG = MediaType.parse("image/jpg");
    try {
        OkHttpClient client = new OkHttpClient();

        Log.d("test",data.getFileParam());

        RequestBody requestBody = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)
                .addFormDataPart("bunting", data.getParam("bunting"))
                .addFormDataPart("dangler", data.getParam("dangler"))
                .addFormDataPart("poster", data.getParam("poster"))
                .addFormDataPart("tearPad", data.getParam("tearPad"))
                .addFormDataPart("leafLet", data.getParam("leafLet"))
                .addFormDataPart("outlet_category", "")
                .addFormDataPart("dealerName", data.getParam("dealerName"))
                .addFormDataPart("brouchers", data.getParam("brouchers"))
                .addFormDataPart("wobblers", data.getParam("wobblers"))
                .addFormDataPart("tentCard", data.getParam("tentCard"))
                .addFormDataPart("others", data.getParam("others"))
                .addFormDataPart("photo", "1.jpg",
                        RequestBody.create(MEDIA_TYPE_JPG, new File(data.getFileParam())))
                .build();

        Request request = new Request.Builder()
                .url(data.getUrl())
                .post(requestBody)
                .build();

        Response response = client.newCall(request).execute();
        if (!response.isSuccessful()) throw new …

我有点想做一台老虎机.要创建老虎机影响我从包装器中删除第一个div并将其添加回底部.当我使用值时,onClick事件工作正常,1000ms但当我使用像100msinterval这样的东西时,我需要快速点击多次以便注册点击事件.为什么会这样？

另外在触摸屏上(在我的手机上查看)我没有遇到这个问题.

setInterval(function() {

  swap_box();
}, 100);

function swap_box() {
  let first_box = document.getElementsByClassName("box")[0];
  first_box.remove();
  document.getElementsByClassName("div-wrapper")[0].appendChild(first_box);

  first_box.addEventListener("click", function() {
    console.log(this.innerText);
  });

}

.box {
  width: 100px;
  height: 50px;
  border: 1px solid black;
}

<div class="div-wrapper">
  <div class="box">0</div>
  <div class="box">1</div>
  <div class="box">2</div>
  <div class="box">3</div>
  <div class="box">4</div>
  <div class="box">5</div>
  <div class="box">6</div>
  <div class="box">7</div>
</div>
