我正在尝试DropboxSync在现有的Android应用程序中实现API.
我已下载DropboxSyncAPI并复制了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.

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); 
....
}
....
}
