1Change log for Android SDK Tools. 2 3Revision 20: 4- Ant build system: 5 * the location of the SDK can now be set through the ANDROID_HOME 6 environment variable (requires updating the project's build.xml file) 7 * Fixed issues with compilation, deployment of test projects and running tests. 8 Both separate test projects and self-contained app+test projects now work. 9 10Revision 19: 11- Fix GPU rendering 12 13Revision 18: 14* Fix Ant issues where some jar libraries in libs/ are not picked in some 15 cases 16* New version of SdkController 17 18Revision 17: 19* Bug fixes. 20* ProGuard updated to version 4.7. In addition to many new features, 21 this will fix the "Conversion to Dalvik format failed with error 1" 22 error some users have experienced. 23* The default proguard.cfg file has been updated with better 24 flags. 25* Lint now checks Java code, and checks which previously performed 26 pattern based searches in the Java code (such as the unused resource 27 check) have been rewritten to use the more accurate Java parse 28 trees. 29* Lint supports library projects, so for example the unused resource 30 check will properly handle resources declared in a library project 31 and referenced in a downstream project. 32* Lint warnings can be suppressed in Java code with the new 33 @SuppressLint annotation, and in XML files with the new tools: 34 namespace and ignore-attribute. 35* New lint checks: 36 * Find Android API calls that require a version of Android higher 37 than the minimum supported version. You can use the new @TargetApi 38 annotation to specify local overrides for conditionally loaded 39 code. 40 * Find object allocations within onDraw, onMeasure and onLayout 41 calls 42 * Find usages of HashMap<Integer,X> which can be replaced by the 43 more efficient SparseArray, SparseIntArray or SparseBooleanArray 44 * Find typos in XML namespace declarations, as well as unused custom 45 namespace declarations and usages of custom namespaces in library 46 projects which do not yet work 47 * Find manifest files which declare more than one <uses-sdk> 48 elements, or which fail to declare minSdkVersion or 49 targetSdkVersion 50 * Check dialog button order such that OK/Cancel are in the right 51 order (depending on the target version of Android), that they are 52 using the standard case ("OK", not "Ok" or "ok" etc), and that 53 there aren't any Back buttons. 54 * Check menus to ensure that they are using "ifRoom" instead of 55 "always" for the showAsAction attribute (unless it's used 56 sparingly) 57 * Find hardcoded android:debuggable attributes on <application> 58 elements. This can lead to accidentally leaving debug information 59 in published applications. 60 * Find errors in format strings. This includes inconsistencies 61 between translated versions, as well as incompatible types 62 declared in XML and supplied in the String.format call in Java. 63 * Find incorrect casts in Java code where the cast is incompatible 64 with the view type declared in XML layouts. 65 * Find hardcoded references to "/sdcard" in Java code; these should 66 be using Environment.getExternalStorageDirectory().getPath() 67 instead 68 * Find "import android.R" statements in Java code, which can lead to 69 confusing compilation error messages 70 * Find Java code which creates world-writeable files (which can lead 71 to security problems) 72 * Find references to private resources (which can lead to runtime 73 errors on devices that do not provide the resource, since private 74 resources may disappear any time, and may not be present on all 75 platforms.) 76 * Find invalid @id references (where for example a RelativeLayout 77 references an id that does not exist anywhere). If no match is 78 found, it looks for spelling mistakes and suggests other similar 79 ids in the error message. 80 * Finds method calls to java.lang.Math where a float variable is 81 cast to a double and/or the return value is cast to a float, and 82 suggests replacing it with the equivalent android.util.FloatMath 83 method. 84 * Finds calls to a getter on the same class where a field could be 85 accessed instead. 86 * Find XML files using a different encoding format than UTF-8, since 87 this can lead to subtle bugs (and lint was fixed to properly use 88 the specified encoding) 89 * Find XML resource files that contain text which should not be 90 there (such as in layouts). This can identify accidentally 91 malformed documents which happen to be valid XML, such as a 92 missing "<" tag opening character. 93 * Find style references which lead to cycles, such as extending 94 self. 95 96Revision 16: 97* New "lint" tool which scans Android project trees for potential 98 problems such as missing translations, duplicate ids between layouts 99 that include each other, using px instead of dp units, hardcoded 100 strings, missing contentDescriptions, obsolete Proguard 101 configuration files, etc. For a full list of available issues run 102 "lint --show" (and see eclipse/changes.txt for further details). 103* layoutopt was removed; its functionality is replaced by the new lint 104 tool 105 106Revision 14: 107 108- Build performance improvements: 109 * resource compilation and packaging now properly use dependency to only 110 be executed if a resource changed. 111 * Optimized resource compilation for projects with libraries. This should 112 speed up this phase significantly for large projects with libraries. 113 * PNG files that are optimized during resource packaging are now cached 114 and only re-optimized if they changed instead of doing at every build. 115- New library project mechanism: 116 * 117 118Revision 13: 119 120Revision 12: (07/2011): 121- The AVD manager and emulator can now use system images compiled for ARM v7 and 122 x86 CPUs. 123 124Revision 11 (05/2011): 125- See eclipse/changes.txt for ADT related changes. 126 127Revision 10 (02/2011): 128- The tools now automatically generate Java Programming Language 129 source files (in the gen directory) and bytecode (in the res/raw 130 directory) from your native .rs files 131 132Revision 9 (01/2011): 133- Fix packaging issue that broke draw9patch 134- Ant build rules will now check the Ant version and fail if it's older than 1.8 135- Fix "folder locked" errors when installing packages in SDK Manager on Windows. 136- Support https proxy when installing from SDK Manager. 137- SDK Manager now suggests to install missing base platform for add-ons. 138- Default proguard config file changes: 139 * ignore classes extending android.preference.Preference 140 * ignore classes extending android.app.backup.BackupAgentHelper 141- Ant lib rules now allow for overriding java.encoding, java.source, and java.target 142- Default encoding for Ant javac is now UTF-8 143- Logcat view in DDMS now properly displays UTF-8 characters. 144 145 146Revision 8 (12/2010): 147- New SDK component: platform-tools. This makes all platforms use the same 148 latest version of aapt/aidl/dx. 149- Support for true debug build. No need to change the value of debuggable in 150 the Android Manifest. 151 "ant debug" will automatically insert debuggable==true, while "ant release" 152 will not. 153 If debuggable=true is set, then "ant release" will actually do a debug build. 154- Automatic Proguard support in release builds. Only need to have a proguard.config 155 property in default.properties that points to a proguard config file. 156- new overridable Ant javac properties: java.encoding, java.source, and java.target 157 (default to "ascii", "1.5" and "1.5") 158 159 160Revision 7 (09/2010): 161- Support for Ant rules provided by the Tools components (override the one in 162 the platform component) 163- Added support for libraries with library dependencies. 164- Support for aidl files in library projects. 165- Support for extension targets in Ant build to perform tasks between the 166 normal tasks: -pre-build, -pre-compile, -post-compile. 167- Headless SDK update. See 'android -h update sdk' for more info. 168- Fixed location control in DDMS to work in any locale not using '.' as a 169 decimal point. 170 171 172Revision 6 (05/2010) 173- Support for library project to share code/resources among projects 174 - Updated Ant rules and custom tasks 175 - New "android create lib-project", "android update lib-project" actions. 176 - New parameter for "android update project" 177 178 179Revision 5 (03/2010): 180- AVD/SDK Manager: 181 - Fixed SSL download for the standalone version of the SDK Updater. 182 - Fixed issue with 64bit JVM on windows. 183 - Add support for samples components. 184 - improved support for dependency between components. 185 - AVDs now sorted by API level. 186 - Prevent deletion of running AVDs. 187 - Settings are now automatically saved, no need to click Apply. 188- Emulator now requires sd card to be 9MB and above. 189- Fixed layoutopt.bat to correctly execute on Windows. 190 191
