java.lang.NoClassDefFoundError:无法解决以下问题:Ljava/time/LocalDate;错误 [英] java.lang.NoClassDefFoundError: Failed resolution of: Ljava/time/LocalDate; error
问题描述
我尝试了一切,但错误没有得到解决
I tried everything, but the error not getting solved
这是我的代码:
public String[] getWeekDays() {
LocalDate today = LocalDate.now();
LocalDate monday = today;
LocalDate tue = today;
LocalDate wed = today;
LocalDate thur = today;
LocalDate fri = today;
LocalDate sat = today;
LocalDate sunday = today;
while (sunday.getDayOfWeek() != DayOfWeek.SUNDAY){
sunday = sunday.minusDays(1);
}
while (monday.getDayOfWeek() != DayOfWeek.MONDAY){
monday = monday.minusDays(1);
}
while (tue.getDayOfWeek() != DayOfWeek.TUESDAY){
tue = tue.plusDays(1);
}
while (wed.getDayOfWeek() != DayOfWeek.WEDNESDAY){
wed = wed.plusDays(1);
}
while (thur.getDayOfWeek() != DayOfWeek.THURSDAY){
thur = thur.plusDays(1);
}
while (fri.getDayOfWeek() != DayOfWeek.FRIDAY){
fri = fri.plusDays(1);
}
while (sat.getDayOfWeek() != DayOfWeek.SATURDAY){
sat = sat.plusDays(1);
}
String[] days = {String.valueOf(sunday),String.valueOf(monday), String.valueOf(tue), String.valueOf(wed),
String.valueOf(thur), String.valueOf(fri), String.valueOf(sat)};
return days;
}
我已编写代码以获取一个星期的日期.当我运行此代码时,LocalDate.now();出现错误.该错误是"java.lang.NoClassDefFoundError:无法解决以下问题:Ljava/time/LocalDate;". 我已经在网上搜索了.有人说它要求API级别至少为27.我对API 27级别感到厌倦,但该错误未得到解决.我的目标设备更多地是我需要在此API级别上运行的API 26.并且还尝试添加编译" java.time:LocalTime:1.8".这也是行不通的. 请帮助我...
I have written the code to get dates of one week. When I running this code, i am getting an error at LocalDate.now();. The error is "java.lang.NoClassDefFoundError: Failed resolution of: Ljava/time/LocalDate;". I have searched on the net. Some are saying it requires API level min 27. I have tired on API 27 level but the error didn't get resolved. More ever my target device is API 26 I needed to run on this API level. And also tried adding "compile "java.time:LocalTime:1.8" ". This one also doesn't work. Please help me...
推荐答案
NoClassDefFoundError
-如果Java虚拟机或 ClassLoader实例尝试加载类的定义(如 普通方法调用的一部分或创建新实例的一部分 使用新的表达式),则无法定义该类 找到了.
NoClassDefFoundError
-Thrown if the Java Virtual Machine or a ClassLoader instance tries to load in the definition of a class (as part of a normal method call or as part of creating a new instance using the new expression) and no definition of the class could be found.
LocalDate today = LocalDate.now(); // Added 1.8

请确保您已在build.gradle
部分中添加了此内容.
Make sure, You added this in your build.gradle
section.
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
仅供参考
java.time
程序包仅在API 26中添加.
java.time
package was added only in API 26.
所以,您应该设置
minSdkVersion 26
此后, Clean-Rebuild-Gradle
.
After that, Clean-Rebuild-Gradle
