在获得65k方法限制后,我实现了多索引。在实现多索引之后,我可以运行应用程序。但是现在我从外部jar中得到了一个类的错误noclasdeffounderror。
这是我的毕业档案--
dependencies {
compile project(':pull-to-refresh')
compile fileTree(dir: 'libs', include: '*.jar')
compile project(':gson-2.2.2')
compile files('libs/android-support-multidex.jar')
compile 'com.android.support:appcompat-v7:21.0.0'
compile 'com.google.android.gms:play-services:6.1.71'
compile 'com.android.support:support-v4:21.0.0'
}
android {
compileSdkVersion 21
buildToolsVersion '21.1.1'
packagingOptions {
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/NOTICE.txt'
}
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot('tests')
// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot('build-types/debug')
release.setRoot('build-types/release')
}
dexOptions {
preDexLibraries = false
}
afterEvaluate {
tasks.matching {
it.name.startsWith('dex')
}.each { dx ->
if (dx.additionalParameters == null) {
dx.additionalParameters = ['--multi-dex']
} else {
dx.additionalParameters += '--multi-dex'`enter code here`
}
}
}
}
最佳答案
我可以通过确保multidex.install行在调用super.attachbasecontext之后修复这个问题。如果在super.attach之前调用install,显然它没有正确注册。不过,简单地更改应用程序类以扩展多索引应用程序(而不是应用程序)可能是更好的选择。
注意:扩展multidexapplication之后,不再需要重写attachbasecontext并调用multidex.install(this)。如果您查看multidexapplication(here)的源代码,您将看到该类的全部用途是为您调用install。
google(posted here)的官方说明为您指出了multidexapplication(posted here)的文档,该页面包含了解决此问题的多个选项的说明,但我第一次错过了,因此我相信许多其他人也会这样做。
