错误。

我的代码是这样的，

list .xml

        <!-- For Dropbox -->
        <activity android:name="com.dropbox.sync.android.DbxAuthActivity" />
        <activity
            android:name="com.dropbox.client2.android.AuthActivity"
            android:launchMode="singleTask" >
            <intent-filter>
                <data android:scheme="db-XXXXXXXXXXXXXX" />
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.BROWSABLE" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
        <service
            android:name="com.dropbox.sync.android.DbxSyncService"
            android:enabled="true"
            android:exported="false"
            android:label="Dropbox Sync" />

我还添加了 build.gradle 就像，

dependencies {
    compile files('libs/dropbox-sync-sdk-android.jar')
    compile files("$buildDir/native-libs/native-libs.jar")
    compile 'com.android.support:support-v4:18.0.0'
}
task nativeLibsToJar(type: Zip) {
    destinationDir file("$buildDir/native-libs")
    baseName 'native-libs'
    extension 'jar'
    from fileTree(dir: 'libs', include: '**/*.so')
    into 'lib/'
}
tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn nativeLibsToJar
}

当我执行

mDbxAcctMgr = DbxAccountManager.getInstance(getApplicationContext(), appKey, appSecret);

此代码出现错误。

使用您的应用 key 将行“db-XXXXXXXXXXXXXX”更改为“db-jd7ld246chdlkej”。

  <activity
  android:name="com.dropbox.client2.android.AuthActivity"
  android:launchMode="singleTask"
  android:configChanges="orientation|keyboard">
  <intent-filter>
    <!-- Change this to be db- followed by your app key -->
    <data android:scheme="db-jd7ld246chdlkej" />
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.BROWSABLE"/>
    <category android:name="android.intent.category.DEFAULT" />
  </intent-filter>
</activity>
