手机rom的那些坑

http://blog.csdn.net/waylife/article/details/44315103

最近在开发Android桌面快捷方式的时候遇到了一些坑，具体来说就是在某些手机上无法判断已存在的快捷方式，细追了一下发现是ROM系统修改了Android的launcher路径导致无法找到正确的桌面去查找相应的桌面图标。

具体的方法

public booleanhasShortcut(Activity activity,String shortcutName) {

String url ="";

url ="content://"+ getAuthorityFromPermission(activity,"com.android.launcher.permission.READ_SETTINGS") +"/favorites?notify=true";

ContentResolver resolver = activity.getContentResolver();

Cursor cursor = resolver.query(Uri.parse(url), newString[]{"title"},"title=?", newString[]{shortcutName}, null);

if(cursor !=null&& cursor.moveToFirst()) {

cursor.close();

return true;

}

returnhasShortcut2(activity,shortcutName);

}

privateStringgetAuthorityFromPermission(Context context,String permission) {

if(permission ==null)

return null;

List packs = context.getPackageManager().getInstalledPackages(PackageManager.GET_PROVIDERS);

if(packs !=null) {

for(PackageInfo pack : packs) {

ProviderInfo[] providers = pack.providers;

if(providers !=null) {

for(ProviderInfo provider : providers) {

//使用正则去匹配launcher 信息

String valse =".*launcher.*settings$";

Pattern pat = Pattern.compile(valse);

Matcher mat = pat.matcher(provider.authority);

if(mat.find()) {

returnprovider.authority;

}

if(permission.equals(provider.readPermission))

returnprovider.authority;

if(permission.equals(provider.writePermission))

returnprovider.authority;

}

}

}

}

return null;

}
