android – Dropbox Sync API – 不满意的链接错误

2019-09-27 19:24:49 阅读：193 来源： 互联网

我正在尝试在现有的Android应用程序中实现DropboxSync API.
我已经下载了DropboxSync API并复制了我的Application的lib文件夹中的所有库.
我还将Native Library位置指向libDropboxSync.so所在的libs文件夹.

的Manifest.xml

....
        <!-- Dropbox Activities -->
    <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-intentionally-hidden-app-key" />

            <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" />

Main_Activity.java

public class Activity_Main extends Activity implements OnClickListener,
OnItemClickListener, OnTouchListener {
....
....
....
private DbxAccountManager mDbxAcctMgr;

onCreate(....)
{
//Application giving FATAL EXCEPTION on the line below.
mDbxAcctMgr = DbxAccountManager.getInstance((Activity)Activity_Main.this, DROPBOX_APP_KEY, DROPBOX_APP_SECRET); 
....
}
....
}

我已经尝试过这个解决方案：Error in dropboxSync: findlibrary returned null但它不适用于我.所以请不要将此问题标记为重复.

非常感谢任何帮助,谢谢.

解决方法:

libs目录下的armeabi-v7a文件夹中缺少libDropboxSync.so.
我将libDropboxSync.so从armeabi-v7文件夹复制到libs目录下的armeabi-v7a文件夹,并且库已成功加载.
由于我使用Google-Nexus-7第二代进行调试,因此armeabi-v7a文件夹中的DropboxSync库是必须的.
