packageInstalled函数的第二个参数returnCode的源码解读

 http://www.eoeandroid.com/forum.php?mod=viewthread&tid=328636

这几天在弄安装的事情，发现很多安装包不能安装成功。IPackageInstallObserver会用回调函数packageInstalled(String packageName, int returnCode)告诉我们returnCode安装结果。

    安卓源码中是这么定义这些returnCode的：
     public static final int INSTALL_SUCCEEDED = 1;

    /**
     * Installation return code: this is passed to the {@link IPackageInstallObserver} by
     * {@link #installPackage(android.net.Uri, IPackageInstallObserver, int)} if the package is

下面一一来看一下每个对应的意义：
《1》
public static final int INSTALL_SUCCEEDED = 1;
这个自不用说，就是你安装成功了。

《-1》public static final int INSTALL_FAILED_ALREADY_EXISTS = -1;
大侠，我都已经安装了啊，你还装

《-2》public static final int INSTALL_FAILED_INVALID_APK = -2;
文件无效啊，请看看路径是否对，再看看权限是不是rw-rw-rw-啊

《-3》 public static final int INSTALL_FAILED_INVALID_URI = -3;
靠，这个文件路径根本无法解析嘛！请用英文命名你的apk包。

《-4》public static final int INSTALL_FAILED_INSUFFICIENT_STORAGE = -4;
装了你我就满了，拿什么装其他东西，fk

《-5》 public static final int INSTALL_FAILED_DUPLICATE_PACKAGE = -5;
已经有和我名字一样的一共用了，请把那个冒牌货删除好吗？

《-6》public static final int INSTALL_FAILED_NO_SHARED_USER = -6;
共享用户都不存在，你搞什么哦

《-7》public static final int INSTALL_FAILED_UPDATE_INCOMPATIBLE = -7;
不能更新，请卸载原来的版本，并把data剩余的东西弄干净

《-8》public static final int INSTALL_FAILED_SHARED_USER_INCOMPATIBLE = -8;
我们是共享用户啊，为什么给我的签名不一样

《-9》 public static final int INSTALL_FAILED_MISSING_SHARED_LIBRARY = -9;
老子的LIBRARY呢，去哪里了？

《-10》public static final int INSTALL_FAILED_REPLACE_COULDNT_DELETE = -10;
LIBRARY有是有，但是用不了额。。。

《-11》public static final int INSTALL_FAILED_DEXOPT = -11;
空间不足或者验证失败了

《-12》public static final int INSTALL_FAILED_OLDER_SDK = -12;
安装包要求的安卓版本太高了啊，4.5的平台滚粗，还是1.6好

《-13》public static final int INSTALL_FAILED_CONFLICTING_PROVIDER = -13;
Provider已经被别人定义了啊，你换个名字吧亲

《-14》public static final int INSTALL_FAILED_NEWER_SDK = -14;
哥，你还真把1.6的应用往4.4的手机上装啊。

《-15》public static final int INSTALL_FAILED_TEST_ONLY = -15;
只供测试，你哪来的包？

《-16》 public static final int INSTALL_FAILED_CPU_ABI_INCOMPATIBLE = -16;
哥，你调底层的东西，手机cpu办不到啊。。。

《-17》public static final int INSTALL_FAILED_MISSING_FEATURE = -17;
你要的效果我没有，请把对应部分注释掉


《-18》  public static final int INSTALL_FAILED_CONTAINER_ERROR = -18;
你说装哪就装哪？还是给系统一个选择吧，用auto最好了



《-19》  public static final int INSTALL_FAILED_INVALID_INSTALL_LOCATION = -19;
路径不对


《-20》public static final int INSTALL_FAILED_MEDIA_UNAVAILABLE = -20;
你把我当U盘用，还要同时在我上面装东西，你还有良心吗

《-100》 public static final int INSTALL_PARSE_FAILED_NOT_APK = -100;
这个好像是zip，不是apk


《-101》public static final int INSTALL_PARSE_FAILED_BAD_MANIFEST = -101;
MANIFEST啊，多少次死在你手里

《-102》public static final int INSTALL_PARSE_FAILED_UNEXPECTED_EXCEPTION = -102;
解析失败了，也许你是把txt文件改成.apk文件了，但是本质是不会变的


《-103》public static final int INSTALL_PARSE_FAILED_NO_CERTIFICATES = -103;
你会签名吗。。。

《-104》 public static final int INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES = -104;
签名是会签了，但是要一致哦



《-105》public static final int INSTALL_PARSE_FAILED_CERTIFICATE_ENCODING = -105;


签名解码失败   

《-106》 public static final int INSTALL_PARSE_FAILED_BAD_PACKAGE_NAME = -106;
有包名吗，正确吗

《-107》public static final int INSTALL_PARSE_FAILED_BAD_SHARED_USER_ID = -107;
共享用户有吗，名字对吗


《-108》 public static final int INSTALL_PARSE_FAILED_MANIFEST_MALFORMED = -108;
在检查检查MANIFEST吧

《-109》public static final int INSTALL_PARSE_FAILED_MANIFEST_EMPTY = -109;
我靠，你这个应用啥也么木有啊。


《-110》public static final int INSTALL_FAILED_INTERNAL_ERROR = -110;
