Android Question No data access with release.

Vbxler · Aug 18, 2015

I have created an application where I read data from a MySQL database. Access to the database is working under debug mode, but not under release mode.
The Library mySQL I use so:

B4X:

'Connecting to database
DB.setDatabase("mysql_Server","DB_Name","user","Passwort")
'Query the data
Liste = DB.Query("select DATE_TIME, CPU_STATUS from TBL_MESSWERT;")

If Liste.IsInitialized=False Then
    Msgbox("No data access!","Warnung")
Else
   'Here the data are evaluated
End If

But it will always output the Msgbbox under Release and Debug (Rapid) it works. Has one of you a an idea what could be wrong?

I use BVA version 5.20, phone with Android 4.2.2, Java 8.0.600.26
Thanks for any help!

Thanks for the hint!
It works now, I have added the first two lines:

B4X:

AddManifestText(
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-sdk android:minSdkVersion="10" android:targetSdkVersion="17"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
SetApplicationAttribute(android:theme, "@android:style/Theme.Holo")

Is that correct?

Search the forum for, "AddPermission"
You'll find a list with all possible permissions. Just copy the two needed lines and add them at the end of your manifesteditor

REMOVE what you did now

So it should probably be right:

B4X:

AddManifestText(
<uses-sdk android:minSdkVersion="10" android:targetSdkVersion="17"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
SetApplicationAttribute(android:theme, "@android:style/Theme.Holo")
'End of default text.

AddPermission(android.permission.INTERNET)

Have the Manifest Editor never used, Thanks for the help!
