1 Change log for Android SDK Tools. 2 3 Revision 20: 4 - Ant build system: 5 - Ant build system: 6 * the location of the SDK can now be set through the ANDROID_HOME 7 environment variable (requires updating the project's build.xml file) 8 * Fixed issues with compilation, deployment of test projects and running tests. 9 Both separate test projects and self-contained app+test projects now work. 10 * Aidl files from library projects are now in the import list. 11 12 Revision 19: 13 - Fix GPU rendering 14 15 Revision 18: 16 * Fix Ant issues where some jar libraries in libs/ are not picked in some 17 cases 18 * New version of SdkController 19 20 Revision 17: 21 * Bug fixes. 22 * ProGuard updated to version 4.7. In addition to many new features, 23 this will fix the "Conversion to Dalvik format failed with error 1" 24 error some users have experienced. 25 * The default proguard.cfg file has been updated with better 26 flags. 27 * Lint now checks Java code, and checks which previously performed 28 pattern based searches in the Java code (such as the unused resource 29 check) have been rewritten to use the more accurate Java parse 30 trees. 31 * Lint supports library projects, so for example the unused resource 32 check will properly handle resources declared in a library project 33 and referenced in a downstream project. 34 * Lint warnings can be suppressed in Java code with the new 35 @SuppressLint annotation, and in XML files with the new tools: 36 namespace and ignore-attribute. 37 * New lint checks: 38 * Find Android API calls that require a version of Android higher 39 than the minimum supported version. You can use the new @TargetApi 40 annotation to specify local overrides for conditionally loaded 41 code. 42 * Find object allocations within onDraw, onMeasure and onLayout 43 calls 44 * Find usages of HashMap<Integer,X> which can be replaced by the 45 more efficient SparseArray, SparseIntArray or SparseBooleanArray 46 * Find typos in XML namespace declarations, as well as unused custom 47 namespace declarations and usages of custom namespaces in library 48 projects which do not yet work 49 * Find manifest files which declare more than one <uses-sdk> 50 elements, or which fail to declare minSdkVersion or 51 targetSdkVersion 52 * Check dialog button order such that OK/Cancel are in the right 53 order (depending on the target version of Android), that they are 54 using the standard case ("OK", not "Ok" or "ok" etc), and that 55 there aren't any Back buttons. 56 * Check menus to ensure that they are using "ifRoom" instead of 57 "always" for the showAsAction attribute (unless it's used 58 sparingly) 59 * Find hardcoded android:debuggable attributes on <application> 60 elements. This can lead to accidentally leaving debug information 61 in published applications. 62 * Find errors in format strings. This includes inconsistencies 63 between translated versions, as well as incompatible types 64 declared in XML and supplied in the String.format call in Java. 65 * Find incorrect casts in Java code where the cast is incompatible 66 with the view type declared in XML layouts. 67 * Find hardcoded references to "/sdcard" in Java code; these should 68 be using Environment.getExternalStorageDirectory().getPath() 69 instead 70 * Find "import android.R" statements in Java code, which can lead to 71 confusing compilation error messages 72 * Find Java code which creates world-writeable files (which can lead 73 to security problems) 74 * Find references to private resources (which can lead to runtime 75 errors on devices that do not provide the resource, since private 76 resources may disappear any time, and may not be present on all 77 platforms.) 78 * Find invalid @id references (where for example a RelativeLayout 79 references an id that does not exist anywhere). If no match is 80 found, it looks for spelling mistakes and suggests other similar 81 ids in the error message. 82 * Finds method calls to java.lang.Math where a float variable is 83 cast to a double and/or the return value is cast to a float, and 84 suggests replacing it with the equivalent android.util.FloatMath 85 method. 86 * Finds calls to a getter on the same class where a field could be 87 accessed instead. 88 * Find XML files using a different encoding format than UTF-8, since 89 this can lead to subtle bugs (and lint was fixed to properly use 90 the specified encoding) 91 * Find XML resource files that contain text which should not be 92 there (such as in layouts). This can identify accidentally 93 malformed documents which happen to be valid XML, such as a 94 missing "<" tag opening character. 95 * Find style references which lead to cycles, such as extending 96 self. 97 98 Revision 16: 99 * New "lint" tool which scans Android project trees for potential 100 problems such as missing translations, duplicate ids between layouts 101 that include each other, using px instead of dp units, hardcoded 102 strings, missing contentDescriptions, obsolete Proguard 103 configuration files, etc. For a full list of available issues run 104 "lint --show" (and see eclipse/changes.txt for further details). 105 * layoutopt was removed; its functionality is replaced by the new lint 106 tool 107 108 Revision 14: 109 110 - Build performance improvements: 111 * resource compilation and packaging now properly use dependency to only 112 be executed if a resource changed. 113 * Optimized resource compilation for projects with libraries. This should 114 speed up this phase significantly for large projects with libraries. 115 * PNG files that are optimized during resource packaging are now cached 116 and only re-optimized if they changed instead of doing at every build. 117 - New library project mechanism: 118 * 119 120 Revision 13: 121 122 Revision 12: (07/2011): 123 - The AVD manager and emulator can now use system images compiled for ARM v7 and 124 x86 CPUs. 125 126 Revision 11 (05/2011): 127 - See eclipse/changes.txt for ADT related changes. 128 129 Revision 10 (02/2011): 130 - The tools now automatically generate Java Programming Language 131 source files (in the gen directory) and bytecode (in the res/raw 132 directory) from your native .rs files 133 134 Revision 9 (01/2011): 135 - Fix packaging issue that broke draw9patch 136 - Ant build rules will now check the Ant version and fail if it's older than 1.8 137 - Fix "folder locked" errors when installing packages in SDK Manager on Windows. 138 - Support https proxy when installing from SDK Manager. 139 - SDK Manager now suggests to install missing base platform for add-ons. 140 - Default proguard config file changes: 141 * ignore classes extending android.preference.Preference 142 * ignore classes extending android.app.backup.BackupAgentHelper 143 - Ant lib rules now allow for overriding java.encoding, java.source, and java.target 144 - Default encoding for Ant javac is now UTF-8 145 - Logcat view in DDMS now properly displays UTF-8 characters. 146 147 148 Revision 8 (12/2010): 149 - New SDK component: platform-tools. This makes all platforms use the same 150 latest version of aapt/aidl/dx. 151 - Support for true debug build. No need to change the value of debuggable in 152 the Android Manifest. 153 "ant debug" will automatically insert debuggable==true, while "ant release" 154 will not. 155 If debuggable=true is set, then "ant release" will actually do a debug build. 156 - Automatic Proguard support in release builds. Only need to have a proguard.config 157 property in default.properties that points to a proguard config file. 158 - new overridable Ant javac properties: java.encoding, java.source, and java.target 159 (default to "ascii", "1.5" and "1.5") 160 161 162 Revision 7 (09/2010): 163 - Support for Ant rules provided by the Tools components (override the one in 164 the platform component) 165 - Added support for libraries with library dependencies. 166 - Support for aidl files in library projects. 167 - Support for extension targets in Ant build to perform tasks between the 168 normal tasks: -pre-build, -pre-compile, -post-compile. 169 - Headless SDK update. See 'android -h update sdk' for more info. 170 - Fixed location control in DDMS to work in any locale not using '.' as a 171 decimal point. 172 173 174 Revision 6 (05/2010) 175 - Support for library project to share code/resources among projects 176 - Updated Ant rules and custom tasks 177 - New "android create lib-project", "android update lib-project" actions. 178 - New parameter for "android update project" 179 180 181 Revision 5 (03/2010): 182 - AVD/SDK Manager: 183 - Fixed SSL download for the standalone version of the SDK Updater. 184 - Fixed issue with 64bit JVM on windows. 185 - Add support for samples components. 186 - improved support for dependency between components. 187 - AVDs now sorted by API level. 188 - Prevent deletion of running AVDs. 189 - Settings are now automatically saved, no need to click Apply. 190 - Emulator now requires sd card to be 9MB and above. 191 - Fixed layoutopt.bat to correctly execute on Windows. 192 193
