我的Android ContentProvider找不到ContentResolver
|
我的目标是编写没有Activity的ContentProvider。为了进行测试，我编写了一个测试-在自己的应用程序中进行活动。对于那些想告诉我，Android仍然包含记录器的人，我知道这一点。
这是ContentProvider的一部分
public static final String AUTHORITY = \"de.xyz.android.log4android\";
public static final int LOGGER_ARROW_URI_ID = 1;
public static final String ARROW_CONTENT_TYPE =
\"vnd.de.xyz.android.cursor.dir/vnr.log\";
public static final int LOGGER_ITEM_URI_ID = 2;
public static final String ITEM_CONTENT_TYPE =
\"vnd.de.xyz.android.cursor.item/vnr.log\";
public static final UriMatcher sUriMatcher;
static {
sUriMatcher = new UriMatcher(UriMatcher.NO_MATCH);
sUriMatcher.addURI(AUTHORITY, LOGGER_TABLE, LOGGER_ARROW_URI_ID);
sUriMatcher.addURI(AUTHORITY, LOGGER_TABLE + \"#\", LOGGER_ITEM_URI_ID);
}
public static final Uri CONTENT_URI = Uri.parse(\"content://\"
+ LogServiceProvider.AUTHORITY + \"/logs\");
public static final DefaultLogEntry LOG_ENTRY = null;
//Some more not important code
@Override
public Uri insert(Uri uri, ContentValues initialValues) {
synchronized (this) {
try {
long rowID = dbHelper.getWritableDatabase().insert(LOGGER_TABLE,
null, initialValues);
if (rowID > 0) {
Uri _uri = ContentUris.withAppendedId(CONTENT_URI, rowID);
getContext().getContentResolver().notifyChange(_uri, null);
return _uri;
}
} catch (Exception ex) {
}
throw new SQLException(\"Failed to insert row into \" + uri);
}
}
//Some more not important code
<manifest xmlns:android=\"http://schemas.android.com/apk/res/android\"
package=\"de.xyz.android.logger\"
android:versionCode=\"1\"
android:versionName=\"1.0\">
<provider
android:name=\"de.xyz.android.logger.LogServiceProvider\"
android:authorities=\"de.xyz.android.log4android\"/>
<application android:icon=\"@drawable/icon\" android:label=\"@string/app_name\">
<uses-sdk android:minSdkVersion=\"4\" />
</application>
ContentResolver cr = getContentResolver();
Uri getItem = Uri.parse(\"content://de.xyz.android.log4android/logs\");
ContentValues values = new ContentValues();
values.put(\"level\",\"WARNING\");
values.put(\"time\",\"1986-11-16\");
values.put(\"message\",\"FistTest\");
values.put(\"owner\",\"jsb\");
values.put(\"file\",\"testLog.java\");
values.put(\"line\",\"27\");
Uri newItem = cr.insert(getItem, values);
