#159 Renamed resources leading with "__"

Build tools "1.3.0 rc1" changed the rules for resources. This commit simply removes the lead "__" from the offending resources in the project.

Library leakcanary-android-1.3 is not in list of external libraries
I have a project with lots of dependencies. When I add

dependencies { debugCompile 'com.squareup.leakcanary:leakcanary-android:1.3' releaseCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.3' }

to main build.gradle, leakcanary-android is not in list of external libraries after gradle sync, although leakcanary-analyzer and leakcanary-watcher are there. See screenshot:

On a blank project however everything works fine:

Heap analysis failed for Obfuscated App

Description

I ran the app from android studio setting up LeakCanary for obfuscated apps and it failed during heap analysis. I turned off obfuscation in progaurd-rules.pro and it worked.

Build.VERSION.SDK_INT: 23
Build.MANUFACTURER: LGE
LeakCanary version: 2.2
Analysis duration: 75543 ms
Heap dump file path: /storage/emulated/0/Download/leakcanary-com.colevit.furmate/2020-04-25_23-53-20_181.hprof
Heap dump timestamp: 1587839082676

Steps to Reproduce

hprof: 2020-04-25_23-53-20_181.hprof.zip

Expected behavior: It should analyse the heap and show leak trace with de-obfuscated names.

Version Information

LeakCanary version: 2.2
Android OS version: 23
Gradle version: 5.6.4
Android Gradle plugin version: 3.5.3

Additional Information

This is tested on a release build though I also tested on debug build as well with code obfuscation and it failed.

type: bug

Dependency：

debugImplementation 'com.squareup.leakcanary:leakcanary-android:2.0-beta-3'

不集成的时候，都是可以运行的，一集成之后就跑不了。项目是使用了AndroidX的，语言是java

Edit with translation from Google translate:

When it is not integrated, it can be run, and it cannot run after integration. The project uses AndroidX and the language is java

ViewGroup.ViewLocationHolder leak in Android P

I'm testing my app with the new leak canary and on different devices (as well as virtual devices). everything looks fine on all devices except one device which is the only one running Android 8. the analyzing process looks fine but whenever it finishes it shows a few leaks (which other devices won't show!).

every time I check the trace I end up either with ReportFragment or InputMethodManager.

is anything actually leaking? is this an excluded leak?

thanks in advance

Force Heap dump in tests to allow heap analysis
Problem description

We are using heap dumps in instrumentation tests using InstrumentationLeakDetector.detectLeaks(). The idea is to leverage the heap dump analysis at the end and validate if there's an additional heap size / bitmap count etc. detected, to watchout for any potential memory regressions.

However the logic to get a heap dump trigger is tied to the fact whether a leak was found or could be found.

In many cases the heap dump doesn't get triggered because there are no objects with a weak reference after a GC etc. Even in those cases when there's no leak, we could still have a memory regression and would like to do a heap analysis.

Potential solutions

Allow a way to force trigger heap analysis from tests.
