Annotation processing with kapt Android Studio -


i'm trying use kapt using annotation processor. ran few problems.

annotation processor jar connected way:

    kapt files('libs/processor.jar')     provided files('libs/processor.jar')

1) i'm using javapoet code generation. , saving class way

    javafile javafile = javafile.builder(package, typespec).build();     javafile.writeto(processingenv.getfiler());

but saves build\generated\source\kapt\release, , never debug folder regardless of build variant.

enter image description here

2) second problem generated file doesn't refresh, until press build->rebuild

the kotlin-kapt plugin automatically select correct output directory based on built library/application variant. when building project single com.android.application module, android studio use application variant selected in "build variants" menu.

build variants window

this not true library modules, which, if not configured otherwise, publish release build variant – even when select "debug" modules inside "build variants" menu.

to kapt , running library modules, have 3 options:

  1. in "build variants" window, select "release" library module containing annotated code. tell android studio pick kapt output inside generated/sources/kapt/release/.

  2. in library modules build.gradle set defaultpublishconfig debug (and keep selected variant @ debug too). tell android gradle plugin compile debug library variant instead of default release one.

    android {     defaultpublishconfig "debug" }

  3. you can choose publish both debug , release build variants ant same time, setting publishnondefaults true. in main app module, can reference library module twice, debugcompile , releasecompile configurations. however, note always build both types, though might require debug sources @ time of building, practically doubling compile times.

can replace full join union of left , right join? if no,why? 'yes' if t1 , t2 sets (no duplicated rows), otherwise answer 'no'. create table t1 (i int); create table t2 (i int); insert t1 values (1); insert t1 values (2); insert t1 values (2); insert t2 values (3); full join select * t1 full join t2 on t1.i=t2.i order 1,2 1 (null) 2 2 2 2 (null) 3 union select * t1 left join t2 on t1.i=t2.i union select * t1 right join t2 on t1.i=t2.i order 1,2 1 (null) 2 2 (null) 3 union all select * t1 left join t2 on t1.i=t2.i union select * t1 right join t2 on t1.i=t2.i order 1,2 1 (null) 2 2 2 2 2 2 2 2 (null) 3

iOS: Performance of reloading UIImage(name:...) -

i have tableview , each row has icon. 90% of rows have same icon. in cellforrowatindexpath method load image assets folder this: var cellimage = uiimage(named: "myimage") does pose performance problem? os somehow smart enough it's same image each time? better if loaded image once , saved in class variable , assigned each time? uiimage 's named: api does kind of caching. if @ uiimage's documentation , states: use init(named:in:compatiblewith:) method (or init(named:) method) create image image asset or image file located in app’s main bundle (or other known bundle). because these methods cache image data automatically, recommended images use frequently.
