I’ve been trying to adapt my Android application to fit into the structure of the RobolectricSample so that I can add some tests around my code but I was running into a problem when trying to deploy the application.
To deploy the application you need to run the following command:
mvn package android:deploy
Which was resulting in the following error:
[INFO] UNEXPECTED TOP-LEVEL ERROR: [INFO] java.lang.OutOfMemoryError: Java heap space [INFO] at com.android.dx.rop.code.PlainInsn.withNewRegisters(PlainInsn.java:152) [INFO] at com.android.dx.ssa.NormalSsaInsn.toRopInsn(NormalSsaInsn.java:121) [INFO] at com.android.dx.ssa.back.SsaToRop.convertInsns(SsaToRop.java:342) [INFO] at com.android.dx.ssa.back.SsaToRop.convertBasicBlock(SsaToRop.java:323) [INFO] at com.android.dx.ssa.back.SsaToRop.convertBasicBlocks(SsaToRop.java:260) [INFO] at com.android.dx.ssa.back.SsaToRop.convert(SsaToRop.java:124) [INFO] at com.android.dx.ssa.back.SsaToRop.convertToRopMethod(SsaToRop.java:70) [INFO] at com.android.dx.ssa.Optimizer.optimize(Optimizer.java:102) [INFO] at com.android.dx.ssa.Optimizer.optimize(Optimizer.java:73)
I’d added a few dependencies to the original pom.xml file so I figured on of those must be causing the problem and eventually narrowed it down to be the twitter4j-core library which I had defined like this in the pom.xml file:
<dependency> <groupId>org.twitter4j</groupId> <artifactId>twitter4j-core</artifactId> <version>[2.2,)</version> </dependency>
I found a bug report for the maven-android-plugin which suggested that increasing the heap size might solve the problem.
That section of the pom.xml file ended up looking like this:
<plugin>
<groupId>com.jayway.maven.plugins.android.generation2</groupId>
<artifactId>android-maven-plugin</artifactId>
<version>3.0.0-alpha-13</version>
<configuration>
<sdk>
<platform>10</platform>
<path>/path/to/android-sdk</path>
</sdk>
<dex>
<jvmArguments>
<jvmArgument>-Xms256m</jvmArgument>
<jvmArgument>-Xmx512m</jvmArgument>
</jvmArguments>
</dex>
<undeployBeforeDeploy>true</undeployBeforeDeploy>
</configuration>
<extensions>true</extensions>
</plugin>
That seemed to get rid of the problem but I also tried changing the plugin version to the latest one and that seemed to solve the problem as well without the need to add the JVM arguments:
<plugin>
<groupId>com.jayway.maven.plugins.android.generation2</groupId>
<artifactId>android-maven-plugin</artifactId>
<configuration>
<sdk>
<platform>10</platform>
<path>/path/to/android-sdk</path>
</sdk>
<undeployBeforeDeploy>true</undeployBeforeDeploy>
</configuration>
<extensions>true</extensions>
</plugin>
The latest version is 3.0.2 from what I can tell.
