I am working on an Android library project. I want to distribute this library as JAR to other developers.Before distributing the JAR I want to obfuscate it. I have tried using PROGUARD for this purpose, but its failing at the last step and says <code>The output jar is empty. Did you specify the proper '-keep' options?</code> Can anyone suggest what is going wrong ? =================EDIT : Error Log ======================= <pre><code>ProGuard, version 4.7 Reading program jar [C:\Users\XYZ\Downloads\login.jar] Reading library jar [D:\Softwares\Android SDK\adt-bundle-windows-x86-20130522\sdk\platforms\android-8\android.jar] Note: the configuration refers to the unknown class 'javax.swing.plaf.ComponentUI' Note: the configuration refers to the unknown class 'javax.swing.plaf.ComponentUI' Note: the configuration refers to the unknown class 'javax.swing.JComponent' Note: there were 3 references to unknown classes. You should check your configuration for typos. The output jar is empty. Did you specify the proper '-keep' options? </code></pre> =============== Edit : proguard.cfg ===================== <pre><code>-optimizationpasses 5 -dontusemixedcaseclassnames -dontskipnonpubliclibraryclasses -dontpreverify -verbose -optimizations !code/simplification/arithmetic,!field/*,!class/merging/* -keep public class * extends android.app.Activity -keep public class * extends android.app.Application -keep public class * extends android.app.Service -keep public class * extends android.content.BroadcastReceiver -keep public class * extends android.content.ContentProvider -keep public class * extends android.app.backup.BackupAgentHelper -keep public class * extends android.preference.Preference -keep public class com.android.vending.licensing.ILicensingService -keep public class MyClass extends MyView { public static String GetSessionID () { } } -keepclasseswithmembernames class * { native <methods>; } -keepclasseswithmembernames class * { public <init>(android.content.Context, android.util.AttributeSet); } -keepclasseswithmembernames class * { public <init>(android.content.Context, android.util.AttributeSet, int); } -keepclassmembers enum * { public static **[] values(); public static ** valueOf(java.lang.String); } -keep class * implements android.os.Parcelable { public static final android.os.Parcelable$Creator *; } </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
