Android Studio：应用程序在 API 29 上运行但在 API 26 上崩溃

Question

该应用程序在 API 29 模拟器和 API 24 手机上运行良好，没有任何意外行为，但在 API 26 中崩溃。应用程序在启动时崩溃。 启动画面后。 我对android相当陌生，我不明白为什么会这样。

我的日志文件：

它说“试图绘制太大（113550336bytes）位图。” 但我不知道是哪一个，因为我只有 xml drawable 和 2 png

我的摇篮：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.2"

    defaultConfig {
        applicationId "com.codebees.scaner"
        minSdkVersion 19
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    implementation 'com.google.zxing:core:3.2.1'
    implementation 'com.journeyapps:zxing-android-embedded:3.2.0@aar'

}

任何帮助都感激不尽。 谢谢 ！

编辑：我发现哪个 png 导致了问题，但我不知道如何解决它，我评论了 ImageView 进行测试，它不再崩溃。 这是 ImageView 的原因：

<ImageView
            android:id="@+id/imageView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:visibility="visible"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            app:srcCompat="@drawable/cross"
            tools:ignore="ContentDescription" />

可绘制的十字架是一个 1776x1776 的 alpha png 但它有发光效果我虽然我必须矢量化它但我会失去我的发光效果

Answer 1

我通过将 png 缩小到 1024x1024 和 70kb 大小来解决此问题

似乎现在工作
