为什么我的应用程序无法在较旧的设备上运行？

标签： java android android-studio mobile-application

我的应用程序可以在Android Nougat和Oreo上正常运行，但是当我想以较低的版本（如棒棒糖）打开时无法运行。

我设置了minSdkVersion 15，尽管不起作用。

如果发现任何导致问题的原因，请让我。我在android应用程序开发中是一个新手，这就是为什么不了解这里出了什么问题。任何帮助深表感谢。预先感谢。

以下是我的build.gradle代码： 

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.internexia.app.gemsv1"
        minSdkVersion 15
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation 'com.android.support:support-v4:28.0.0'
    compile 'com.android.support:design:28.0.0'
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

答案 0 :(得分：1)

将所有图像文件从drawable-v24文件夹传输到drawable文件夹。

如果您只是移动文件，错误将消失并且可以正常工作。

答案 1 :(得分：0)

似乎未完全支持某些SVG源。在活动的onCreate() 方法

中添加以下行： 
AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);

并确保您在 XML文件中使用以下属性作为ImageView的属性： app:srcCompact而不是android:src来定义图像。
