ClassNotFoundException error reports when upgrading Android app

由 人走茶凉 提交于 2019-12-01 15:13:02
问题 I've seen quite a few threads about ClassNotFoundException and Android, but I have yet to find what I think is the reason for what I experience. I have an app - Data counter widget - on Android Market. It has 250k+ downloads, and every time I release a new version I get a handful (1-5) of error reports about a ClassNotFoundException to my developer console in Android Market. 29 reports are from unspecified ('OTHER') devices, while two are from the Nexus One. There are two user messages:

classNotFound Exception when using JDBC for MYSQL on Tomcat in eclipse

This seems to be a common problem, but I could not find a working solution. I've looked through dozens of thread and have been working with my teacher. I am trying to connect to MYSQL using JDBC. I'm also using a tomcat server and running xubuntu 12.04. I am getting ClassNotFound exception. I've tried the JDBC mysql-connector-java.jar driver placed in both /tomact/lib and /usr/share/java and have manually built paths in each instance. I've also tried adding paths through deploy assembly. I've tried using EXPORT CLASSPATH. Nothing has worked. I cannot get this exception to stop being thrown.

So i'm developing an app that can scan QR codes. I downloaded the ZXing library, built it using apache ant to get the core.jar, put it in my project folder and added it as a jar to the build path. No when i try do the following: Intent intent = new Intent("com.google.zxing.client.android.SCAN"); intent.putExtra("SCAN_MODE", "QR_CODE_MODE"); startActivityForResult(intent, 0); I get the following error: 08-14 18:52:01.191: E/AndroidRuntime(617): FATAL EXCEPTION: main 08-14 18:52:01.191: E/AndroidRuntime(617): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.android

Error inflating layout with java.lang.ClassNotFoundException

OK now I know that this question has been asked before several times on SO but none of the answers have worked for me. I am attempting to create a custom preference for my project. More specifically it is a preference with a HorizontalListView attached directly underneath it. I basically created it by modifying this code for a SeekBarPreference (which I am also using and is working fine). My ListViewPreference is located in exactly the same folder as the SeelkBarPreference (which, as I said is having no problem) but I am constantly getting a ClassNotFoundException (see logcat below). Here is

问题 I am trying to do a google maps activity but I get a LogCat error and my app crashes. I used the coding provided by android when I registered my API key so I don't know why it doesn't work. I need help solving this.

Really newbie in java, Spanish-speaker, so, ill do my best for you to understand me :). I made a program which manages a mysql database for storing clientes, information about clients, etc. And generates (or trying too...) reports. I installed JasperReports from Eclipse Market (BTW, using Eclipse Kepler). Following some tutorials, i made my way into creating a report by parameters. Its just one parameter to identify one client. Thats not the problem. The problem comes when i click my button to generate the report, which contains the code below: JButton btnOk = new JButton("OK"); btnOk
