android \xxx\libs\ xx.jar系统找不到指定的路径
有可能是需要修改混淆配置。




Eclipse打包时出现export aborted because fatal lint errors were found


参照http://stackoverflow.com/questions/8590908/android-export-aborted-because-fatal-error-were-founds

解决办法：

Project -> properties, find Android Lint Preferences, in top to right click configure workspace settings... -> unclick "Run full error check when exporting app", apply done.

工程项目右键 -> Android Tools -> Clean Lint Markers



Unable to open stack trace file '/data/anr/traces.txt': Permission 多见于这个Activity你没有在AndroidManifest.xml中注册，就会报这样的错误。

所用软件版本：

  spark2.3.0

  kafka 1.10

  IDEA2019.1(spark-streaming-kafka-0-8-2.11-2.3.0)

在用IDEA导入kafka JAR包的时候，一直导入不进去，因为spark-streaming-kafka的jar包和kafka的jar包搞混，把org.apache.kafka.clients.consumer.ConsumerRecord写成org.apache.spark.kafka.clients.consumer.ConsumerRecord，多加了个spark，错误以为kafka是spark包里面的！！！

 

做好记录，供以后参考！！！

jmeter导入jar包提示错误：ERROR o.a.j.JMeter: Uncaught exception

1、jmeter导入jar包后，运行后 提示如下错误

2020-06-29 11:13:27,506 ERROR o.a.j.JMeter: Uncaught exception:

java.lang.IncompatibleClassChangeError: Expected static method my.path.kate.getDt(Ljava/lang/String;Ljava/lang/String;)
2、原因分析

jar冲突，jmeter加载重复的jar包

检查、删除如下目录中的重复包，即可
目录：

D:\apache-jmeter-5.1.1\apache-jmeter-5.1.1\lib

D:\apache-jmeter-5.1.1\apache-jmeter-5.1.1\lib\ext
3、说明
jmeter的jar包存放目录：

目录：

D:\apache-jmeter-5.1.1\apache-jmeter-5.1.1\lib

D:\apache-jmeter-5.1.1\apache-jmeter-5.1.1\lib\ext
注：同一个类包，不能重复放在这些目录下

即使jar包的名称不同，但是classname一样，也不行
