Question

在过去的几天里，我一直试图将git项目https://github.com/spacecowboy/NoNonsense-FilePicker导入到我正在android studio中开发的应用程序中。不幸我尝试从我的程序中启动filePicker活动时因为以下错误而无法执行此操作：

我无法解决此错误。看似导入的filpicker库的路径是错误的，但是路径是正确的。

我的gradle文件如下

apply plugin: 'com.android.application'
apply plugin: 'android'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

configurations{
    all*.exclude module: 'support-v4'
}
defaultConfig {
    applicationId "no.trappsoft.passitory"
    minSdkVersion 19
    targetSdkVersion 21
    multiDexEnabled=true
}
repositories {
    jcenter()
}
buildTypes {
    release {
        minifyEnabled false
        //proguardFiles getDefaultProguardFile('proguard-android.txt'),     
'proguard-rules.txt'
    }
}
}


dependencies {
compile files('libs/android-support-v13.jar')
compile files('libs/sqlcipher-javadoc.jar')
compile files('libs/sqlcipher.jar')
compile 'com.github.clans:fab:1.6.2'
compile 'com.madgag.spongycastle:core:1.53.0.0'
compile 'com.madgag.spongycastle:prov:1.53.0.0'
compile 'com.madgag.spongycastle:pkix:1.53.0.0'
compile 'com.madgag.spongycastle:pg:1.53.0.0'
compile 'com.nononsenseapps:filepicker:2.4.2'

}

我必须添加multiDexEnabled行和配置部分才能使用使用包含的filepicker项目编译应用程序。不过这些构建过程会因其他错误而中断。

代码实际中断的文件位于EditKeys Activity中的以下行：

Intent i = new Intent(EditKeys.this,FilePickerActivity.class);

我的清单文件包含filePicker活动的以下活动定义：

<activity
        android:name="com.nononsenseapps.filepicker.FilePickerActivity"
        android:label="@string/app_name"
        android:theme="@style/FilePickerTheme">
        <intent-filter>
            <action android:name="android.intent.action.GET_CONTENT" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

以下是外部库及其位置的屏幕截图： FilePicker Path Problem

我目前无法做什么。 T任何和所有帮助都非常有用。

无法在DexPathList上找到类
