unit testing - Context cannot be cast to Activity (Android instrumented tests) -


i trying test android app multiple languages (over 40). application behavior configurable firebase remote config - parameters set device locale condition.

my test case requires context cast activity execute production code:

mfirebaseremoteconfig.fetch(cacheexpiration)             .addoncompletelistener((activity) context, new oncompletelistener<void>()             {                 ...             }

i have tried context defined in following way:

context appcontext = instrumentationregistry.gettargetcontext();

but throws:

java.lang.classcastexception: android.app.contextimpl cannot cast android.app.activity

is there simple way achieve this?

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 <...
