Question

I recently implemented the APK Expansion File code, described in http://developer.android.com/guide/market/expansion-files.html, into my app. I updated the manifest, created the Service and Receiver files and update my main activity onCreate() to conform to the instructions in the guide.

I created a signed apk of my app, and uploaded it to my Google Play account, along with the obb file. These were saved as "drafts".

I then used adb to install my signed APK onto my device and ran it and immediately got the following exception:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.myapp/com.example.myapp.MyApp}:
android.database.sqlite.SQLiteException: no such table:

What is interesting is that if I run my app through the Eclipse debugger, I can execute the code that caused the exception, and continue normal processing, getting a message "Download failed because you may not have purchased this app".

Any idea why, on a signed version, there is an SQLite exception in the downloader library, specifically DownloadsDB.java?

我的项目建设目标为2.3.3

I have the Google Play License, Downloader and Zip libraries referenced by my project

我的发言如下:

<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="15" /    
<uses-permission android:name="com.android.vending.CHECK_LICENSE" /
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<service android:name=".MyAppDownloaderService" />
<receiver android:name=".MyAppAlarmReceiver" />

TIA,

Answer 1

我没有得到完全相同的例外,但这可能是你的问题:

下载数据库中的代码。

if (null != cur && cur.moveToFirst()) { ... }

必须改变为:

if (null != cur) { if (cur.moveToFirst()) { ... } }

Answer 2

是的,但目前的做法已经改变。每项申请都至关重要,

这一错误主要出于几个原因,确保:

you are logged in from your test acoount into your device. key are same in your code as well. you have mentioned the size of expansion file in code correctly in bytes. after uploading wait for 3-4 hours, then it will start downloading, instantly it does not work.
