Its present in the rt.jar
. You can use the JarFinder to find jars and classes.
Its present in the lib
folder of jdk installation directory.
Question
When I need to get method signatures for android.content.ContextWrapper
, I go to
"C:\Program Files (x86)\Android\android-sdk\platforms\android-18" where android.jar is placed and then execute
javap -s -classpath android.jar android.content.ContextWrapper > out.txt
Now, I need to get method signatures for java.io.File
. How is corresponding .jar named?
Solution
Its present in the rt.jar
. You can use the JarFinder to find jars and classes.
Its present in the lib
folder of jdk installation directory.
OTHER TIPS
This is rt.jar
from your JRE or JDK, namely inside lib
on the JRE. Given that you are using Windows, I would head to:
C:\program files\java\jdk1.7.0_25\jre\lib
for a JDK (changing the location to your JDK).
android.jar
also has that file, but the former should suffice for a non-android implementation.
As of Android SDK 16 (I haven't tested this in Android 18) android.jar
also has the java.io.File
class.
Try opening it as a ZIP file and see which files it has.
ContentWrapper
is in the android/content
folder.
File
exists in the java/io
folder.
Here are the first few lines of javap output for android.jar
java.io.File
Compiled from "File.java"
public class java.io.File implements java.io.Serializable, java.lang.Comparable<java.io.File> {
public static final char separatorChar;
Signature: C
public static final java.lang.String separator;
Signature: Ljava/lang/String;
public static final char pathSeparatorChar;
Signature: C
public static final java.lang.String pathSeparator;
Signature: Ljava/lang/String;
static final boolean $assertionsDisabled;
Signature: Z
int getPrefixLength();
Signature: ()I
public java.io.File(java.lang.String);
Signature: (Ljava/lang/String;)V
public java.io.File(java.lang.String, java.lang.String);
Signature: (Ljava/lang/String;Ljava/lang/String;)V
It is present in the java runtime library
of java version you are using. For me it is in
/home/aniket/jdk1.7.0_11/jre/lib/rt.jar
Check accordingly.
