android - Too many field references: 70613; max is 65536 -


my project uses these plugins:

  • onesignal
  • googleplayservices
  • adjust
  • google analytics
  • unity iap
  • facebook sdk

those plugins used in every project.

but on field references count

this .aar file list list

what should decrease reference count?

so should decrease reference count ?

you have many plugins many functions/fields. there limit when building unity's editor , have reached limit.

to decrease reference count, have delete these plugins sure need them , deletion may not appropriate solution in case.

the only way around , build android @ moment export project android project build android studio. removes reference limit imposed unity's editor.

edit

i forgot mention have enable multidex after exporting out. since many people go through problem daily, decided add thorough instruction on how fix problem exporting out , how fix without exporting it.

fix exporting project

1a.export unity project android project.

enter image description here

1b.import android studio:

enter image description here

if grade error when importing android studio 1 below:

error:org.gradle.api.internal.tasks.defaulttaskinputs$taskinputunionfilecollection cannot cast org.gradle.api.internal.file.collections.defaultconfigurablefilecollection

enter image description here

in "dependencies" block in "buildscript" block in build.gradle file, change:

classpath 'com.android.tools.build.gradle.2.1.0'

to 

classpath 'com.android.tools.build:gradle:2.2.3'

enter image description here

if export project , still the-same error, need manually enable multidex. below simplified step follow google's doc shown in error:

2.add android:name="android.support.multidex.multidexapplication" > application tag in androidmanifest.xml file.

enter image description here

3.add compile 'com.android.support:multidex:1.0.1' "dependencies" block in build.gradle file.

enter image description here

4.add multidexenabled true "defaultconfig" block in "android" block in build.gradle file.

enter image description here

build apk , see if works. if reference count error gone, stop here.

5.getting gc overhead exception 1 below?

java.lang.outofmemoryerror: gc overhead limit exceeded

increase heap size used when performing dex operation. solution, add following "android" block in build.gradle file:

dexoptions {     javamaxheapsize "4g" }

enter image description here

fix without exporting project

must have unity 5.5 , above this:

1.go <unityinstallationdirecory>\editor\data\playbackengines\androidplayer\tools\gradletemplates, copy maintemplate.gradle file <projectname>assets\plugins\android folder.

2.go <unityinstallationdirecory>\editor\data\playbackengines\androidplayer\apk, copy androidmanifest.xml file <projectname>assets\plugins\android

3.open both maintemplate.gradle , androidmanifest.xml file copied visual studio modification fix exporting project instruction above. skip/ignore step #1a , #1b. steps #2 #5. that's it.

this final maintemplate.gradle should , this final androidmanifest.xml should like. reference purposes. suggest you don't use mine instead follow copy steps above create yours because future unity versions can come different files. want make sure use latest 1 or may have problems building it.

4.build apk , see if works:

enter image description here

--

if reference count error gone, stop here:

5.getting error 1 below?

build failure release builds have signed when using gradle

just sign apk publishing settings in build settings. can create new keystore or use existing one.

enter image description here

6.another error below?

error: avoid hardcoding debug mode; leaving out allows debug , release builds automatically assign 1 [hardcodeddebugmode]

remove android:debuggable="true"> androidmanifest.xml file.

if non exporting solution did not work have use exporting solution.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
