问题出现的原因:
Android studio升级到3.0以上,工程自动会引入Androidx的相关包,当因为某些原因,我们把默认依赖删除以后,就会出现 Android resource linking failed
,错误日志1是缺少 androidx.appcompat:appcompat:1.0.0-alpha1
依赖,错误日志2是缺少 androidx.constraintlayout:constraintlayout:1.1.2
依赖,
compileSdkVersion
版本不对,应该改为 compileSdkVersion 28
解决方案
添加相关依赖即可,如下:
implementation 'androidx.appcompat:appcompat:1.0.0-alpha1' implementation 'androidx.constraintlayout:constraintlayout:1.1.2'
二. java.lang.ClassNotFoundException
Caused by: java.lang.ClassNotFoundException: Didn't find class "android.support.v4.content.FileProvider4Util" on path: DexPathList[[zip file "/data/app/com.hp.temp-1/base.apk"],nativeLibraryDirectories=[/data/app/com.hp.temp-1/lib/arm64, /system/lib64, /vendor/lib64, /system/vendor/lib64, /oem/lib, /oem/lib]] at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56) at java.lang.ClassLoader.loadClass(ClassLoader.java:380) at java.lang.ClassLoader.loadClass(ClassLoader.java:312) at android.app.ActivityThread.installProvider(ActivityThread.java:5962) at android.app.ActivityThread.installContentProviders(ActivityThread.java:5545) at android.app.ActivityThread.handleBindApplication(ActivityThread.java:5484) at android.app.ActivityThread.-wrap2(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1595) at android.os.Handler.dispatchMessage(Handler.java:110) at android.os.Looper.loop(Looper.java:203) at android.app.ActivityThread.main(ActivityThread.java:6251) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1063) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:924) Suppressed: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/support/v4/content/FileProvider; at java.lang.VMClassLoader.findLoadedClass(Native Method) at java.lang.ClassLoader.findLoadedClass(ClassLoader.java:742) at java.lang.ClassLoader.loadClass(ClassLoader.java:362) ... 12 more Caused by: java.lang.ClassNotFoundException: Didn't find class "android.support.v4.content.FileProvider" on path: DexPathList[[zip file "/data/app/com.hp.temp-1/base.apk"],nativeLibraryDirectories=[/data/app/com.hp.temp-1/lib/arm64, /system/lib64, /vendor/lib64, /system/vendor/lib64, /oem/lib, /oem/lib]] at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56) at java.lang.ClassLoader.loadClass(ClassLoader.java:380) at java.lang.ClassLoader.loadClass(ClassLoader.java:312) ... 15 more
原因分析:
build.gradle文件如下
apply plugin: 'com.android.application' apply plugin: 'kotlin-android' apply plugin: 'kotlin-android-extensions' android { compileSdkVersion 28 defaultConfig { applicationId "com.hp.temp" minSdkVersion 15 targetSdkVersion 27 versionCode 1 versionName "1.0" testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version" // implementation 'androidx.appcompat:appcompat:1.0.0-alpha1' implementation 'androidx.constraintlayout:constraintlayout:1.1.2' implementation 'com.android.support:appcompat-v7:27.1.1' testImplementation 'junit:junit:4.12' androidTestImplementation 'androidx.test:runner:1.1.0-alpha3' androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha3' implementation 'com.blankj:utilcode:1.15.0' }
原因我依赖了 implementation 'com.blankj:utilcode:1.15.0'
,其中有个 FileProvider
类找不到,如下:
package android.support.v4.content; import android.support.annotation.Keep; /** * <pre> * author: Blankj * blog : http://blankj.com * time : 2018/04/23 * desc : * </pre> */ @Keep public final class FileProvider4Util extends FileProvider { }
由于androidx的使用,架包的分包方式发生了变化, com.android.support:support-v4
被 androidx.core
代替,但是 utilcode
架包中并没有使用androidx分包结构,所以就存在问题.
解决方案:
1.不使用androidx分包,将
<code>implementation 'androidx.appcompat:appcompat:1.0.0-alpha1'</code> <code> implementation 'com.android.support:appcompat-v7:27.1.1'</code>
虽然后报红,但是不会报错
2.重构到新的androidx命名空间
