Question

某些手机（例如Samsung S6或S7）无法启动我的Android webview应用程序。这是我从谷歌游戏商店得到的：

java.lang.RuntimeException:

这似乎是我的闪屏，就是这样：

activity_main.xml中：

//splashscreen fullscreen
<ImageView
    android:id="@+id/splash1"

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scaleType="centerCrop"
    android:adjustViewBounds="true"
    android:screenOrientation="portrait"
    android:visibility="visible"
    android:src="@drawable/redsplashscreen"
    />

//shows the webview fullscreen
<WebView
    android:id="@+id/web1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:visibility="gone"

MainActivity.java片段：

boolean splashFinished = false;

    @Override
    public void onPageFinished(WebView view, String url) {
        //loads splashscreen once till website is loaded
        if (!splashFinished) {
            //hides loading image
            findViewById(R.id.splash1).setVisibility(View.GONE);
            //shows webview
            findViewById(R.id.web1).setVisibility(View.VISIBLE);
            splashFinished = true;
        }

这里的一些人说我必须将图像从“drawable”文件夹移动到“drawable-xxhd”，我尝试了，但是当我想创建一个APK时，android studio会将其移回并更改代码xml。

BTW图像不是很大，我将大小从1.7MB改为0.7MB。

Answer 1

在我的情况下，有些手机无法处理大飞溅图像文件。我是1.xMB，在减小文件大小后，不再崩溃了。

缩小文件大小。

Answer 2

我有一个解决方案：在android studio中我制作了“drawable-xxhdpi”文件夹（右击“res” - ＆gt; new - ＆gt;目录）。我将相同的splashscreen图像放在此文件夹中。这样，它不会改变aactivity_main.xml的任何内容。
