Question

我的启动画面在模拟器中工作，但是在物理设备上它会崩溃。可能是什么事？

styles.xml

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
</style>

<style name="SplashTheme" parent="AppTheme">
    <item name="android:windowBackground">@drawable/splash_screen</item>
</style>

</resources>

splash.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item
            android:drawable="@drawable/splash_screen"/>

    <item>
        <bitmap
                android:gravity="center"
                android:src="@mipmap/ic_launcher"/>
    </item>

</layer-list>

以上是我为模拟器中使用的启动画面添加的内容。如何使用物理设备（Samsung S8）调试崩溃。

的AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.koolbusiness">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

    <application
      android:name=".MainApplication"
      android:label="@string/app_name"
      android:icon="@mipmap/ic_launcher"
      android:allowBackup="false"
      android:theme="@style/AppTheme">
        <activity
                android:name=".MainActivity"
                android:label="@string/app_name"
                android:theme="@style/SplashTheme"
                android:configChanges="keyboard|keyboardHidden|orientation|screenSize">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
      <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
    </application>

</manifest>

我能够从谷歌应用程序控制台生成这个堆栈跟踪（不会忘记搜索USB驱动程序）。

我在我的应用中使用相同的方法创建了一个启动画面并且对我有用，尝试这些更改并让我知道。

styles.xml - 删除parent="AppTheme"部分，使它看起来像这样

<style name="SplashTheme">
<item name="android:windowBackground">@drawable/splash_screen</item>
</style>

splash.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

   // use a color here instead like the line below
  <item android:drawable="@color/white"/>

  <item>
    <bitmap
            android:gravity="center"
            android:src="@mipmap/ic_launcher"/>
  </item>

</layer-list>

清单 - 使用"@style/SplashTheme"作为应用主题，并从主要活动中删除android:theme="@style/SplashTheme"行。

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.koolbusiness">

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

<application
  android:name=".MainApplication"
  android:label="@string/app_name"
  android:icon="@mipmap/ic_launcher"
  android:allowBackup="false"
  android:theme="@style/SplashTheme">
    <activity
            android:name=".MainActivity"
            android:label="@string/app_name"

  android:configChanges="keyboard|keyboardHidden|orientation|screenSize">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
  <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" 
  />
 </application>

</manifest>
