java - Android 应用程序(Webview)因闪屏而崩溃

Question

某些手机(例如三星 S6 或 S7)无法启动我的 Android Webview 应用程序。这是我从 Google Play 商店获得的:

java.lang.RuntimeException:

这似乎是我的启动画面，就是这样:

activity_main.xml:

//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 fragment :

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;
        }

这里有人说我必须将图像从“drawable”文件夹移动到“drawable-xxhd”，我尝试了它，但是当我想创建APK时，android studio将其移回并更改了xml代码。

顺便说一句，图像并不是很大，我将大小从 1.7MB 更改为 0.7MB。

Answer 1

就我而言，某些手机无法处理大的启动图像文件。 我的是 1.xMB，减小文件大小后，不再崩溃。

减小文件大小。
