Error:(47, 0) Could not get unknown property 'IS_CI_BUILD' for object of type com.android.build.gradle.AppExtension -


after performing rm -rf ~/.gradle , rm -rf ~/.gradle/wrapper/dists (needed in order prevent app applying cached versions of third-party library) can no longer build app, line

buildtypes.each {     it.buildconfigfield 'boolean', 'is_ci_build', is_ci_build }

leads error:

error:(47, 0) not unknown property 'is_ci_build' object of type com.android.build.gradle.appextension.

what possibly reason? this answer infered is_ci_build property should boolean, whenever change true or false , try run app, edit configuration dialog pops in not sure do.

hmm, turns out problematic build.gradle line needs this:

 buildtypes.each {         it.buildconfigfield 'boolean', 'is_ci_build', 'boolean.parseboolean("true")'     }

i opened generated buildconfig class , noticed there 2 ways gradle generates these static variables, either literals this: public static final boolean fabricenabled = true; or this: public static final boolean debug = boolean.parseboolean("true"); (more info here).

my is_ci_build wasn't there, figured reason cannot generate buildconfig class , decided give second method try. worked!

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
