[2011-12-21 00:42:44 - sample] Package the android resources. It will read assets and resources that are
[2011-12-21 00:42:44 - sample] supplied with the -M -A -S or raw-files-dir arguments. The -J -P -F and -R
[2011-12-21 00:42:44 - sample] options control which files are output.
[2011-12-21 00:42:44 - sample]
[2011-12-21 00:42:44 - sample] aapt r[emove] [-v] file.{zip,jar,apk} file1 [file2 ...]
[2011-12-21 00:42:44 - sample] Delete specified files from Zip-compatible archive.
[2011-12-21 00:42:44 - sample]
[2011-12-21 00:42:44 - sample] aapt a[dd] [-v] file.{zip,jar,apk} file1 [file2 ...]
[2011-12-21 00:42:44 - sample] Add specified files to Zip-compatible archive.
[2011-12-21 00:42:44 - sample]
[2011-12-21 00:42:44 - sample] aapt v[ersion]
[2011-12-21 00:42:44 - sample] Print program version.
[2011-12-21 00:42:44 - sample]
[2011-12-21 00:42:44 - sample] Modifiers:
[2011-12-21 00:42:44 - sample] -a print Android-specific data (resources, manifest) when listing
[2011-12-21 00:42:44 - sample] -c specify which configurations to include. The default is all
[2011-12-21 00:42:44 - sample] configurations. The value of the parameter should be a comma
[2011-12-21 00:42:44 - sample] separated list of configuration values. Locales should be specified
[2011-12-21 00:42:44 - sample] as either a language or language-region pair. Some examples:
[2011-12-21 00:42:44 - sample] en
[2011-12-21 00:42:44 - sample] port,en
[2011-12-21 00:42:44 - sample] port,land,en_US
[2011-12-21 00:42:44 - sample] If you put the special locale, zz_ZZ on the list, it will perform
[2011-12-21 00:42:44 - sample] pseudolocalization on the default locale, modifying all of the
[2011-12-21 00:42:44 - sample] strings so you can look for strings that missed the
[2011-12-21 00:42:44 - sample] internationalization process. For example:
[2011-12-21 00:42:44 - sample] port,land,zz_ZZ
[2011-12-21 00:42:44 - sample] -d one or more device assets to include, separated by commas
[2011-12-21 00:42:44 - sample] -f force overwrite of existing files
[2011-12-21 00:42:44 - sample] -g specify a pixel tolerance to force images to grayscale, default 0
[2011-12-21 00:42:44 - sample] -j specify a jar or zip file containing classes to include
[2011-12-21 00:42:44 - sample] -k junk path of file(s) added
[2011-12-21 00:42:44 - sample] -m make package directories under location specified by -J
[2011-12-21 00:42:44 - sample] -u update existing packages (add new, replace older, remove deleted files)
[2011-12-21 00:42:44 - sample] -v verbose output
[2011-12-21 00:42:44 - sample] -x create extending (non-application) resource IDs
[2011-12-21 00:42:44 - sample] -z require localization of resource attributes marked with
[2011-12-21 00:42:44 - sample] localization="suggested"
[2011-12-21 00:42:44 - sample] -A additional directory in which to find raw asset files
[2011-12-21 00:42:44 - sample] -G A file to output proguard options into.
[2011-12-21 00:42:44 - sample] -F specify the apk file to output
[2011-12-21 00:42:44 - sample] -I add an existing package to base include set
[2011-12-21 00:42:44 - sample] -J specify where to output R.java resource constant definitions
[2011-12-21 00:42:44 - sample] -M specify full path to AndroidManifest.xml to include in zip
[2011-12-21 00:42:44 - sample] -P specify where to output public resource definitions
[2011-12-21 00:42:44 - sample] -S directory in which to find resources. Multiple directories will be scanned
[2011-12-21 00:42:44 - sample] and the first match found (left to right) will take precedence.
[2011-12-21 00:42:44 - sample] -0 specifies an additional extension for which such files will not
[2011-12-21 00:42:44 - sample] be stored compressed in the .apk. An empty string means to not
[2011-12-21 00:42:44 - sample] compress any files at all.
[2011-12-21 00:42:44 - sample] --debug-mode
[2011-12-21 00:42:44 - sample] inserts android:debuggable="true" in to the application node of the
[2011-12-21 00:42:44 - sample] manifest, making the application debuggable even on production devices.
[2011-12-21 00:42:44 - sample] --min-sdk-version
[2011-12-21 00:42:44 - sample] inserts android:minSdkVersion in to manifest. If the version is 7 or
[2011-12-21 00:42:44 - sample] higher, the default encoding for resources will be in UTF-8.
[2011-12-21 00:42:44 - sample] --target-sdk-version
[2011-12-21 00:42:44 - sample] inserts android:targetSdkVersion in to manifest.
[2011-12-21 00:42:44 - sample] --max-res-version
[2011-12-21 00:42:44 - sample] ignores versioned resource directories above the given value.
[2011-12-21 00:42:44 - sample] --values
[2011-12-21 00:42:44 - sample] when used with "dump resources" also includes resource values.
[2011-12-21 00:42:44 - sample] changes default encoding for resources to UTF-16. Only useful when API
[2011-12-21 00:42:44 - sample] level is set to 7 or higher where the default encoding is UTF-8.
我之前找不到这个错误，所以请回答这个问题。
最佳答案
试试这个:
更新到 ADT r14 后，转到 Window -> SDK Manager(在 Eclipse 中)
- 选中“存储库”，取消选中“已安装”
- 等待包加载，然后选择所有支持包，全部接受并安装
- 重新启动 Eclipse
现在您可以在新的 ADT r14 上运行您的应用程序，而不会出现“紧缩”错误
