Method Detail

streamToString

public static String streamToString(InputStream is)
                             throws IOException

Throws:

IOException

copyStream

public static void copyStream(InputStream is,
                              OutputStream os,
                              byte[] buffer)
                       throws IOException

Copies all available data from the InputStream into the OutputStream, using the provided buffer. Neither stream is closed during this call.

Throws:

IOException

closeQuietly

public static void closeQuietly(Closeable closeable)

closeOrLog

public static void closeOrLog(Closeable c,
                              String message)

Closes a Closeable, ignoring any IOExceptions raised in the process. Does nothing if the Closeable is null.

Parameters:

c - Closeable to close

getBooleanResourceValue

public static boolean getBooleanResourceValue(Context context,
                                              String key,
                                              boolean defaultValue)

Gets a value for a boolean resource by its name. If a key is not present, the provided default value will be returned.

Tries to look up a boolean value two ways:

1. As a bool resource. A discovered value is returned as-is.
2. As a string resource. A discovered value is turned into a boolean with Boolean.parseBoolean(String) before being returned.

Parameters:

context - Context to use when accessing resources

key - String name of the boolean value to look up

defaultValue - value to be returned if the specified resource could be not be found.

Returns:

String value of the specified property, or an empty string if it could not be found.

getStringResourceValue

public static String getStringResourceValue(Context context,
                                            String key,
                                            String defaultValue)

Gets a value for a string resource by its name. If a key is not present, the provided default value will be returned.

Parameters:

context - Context to use when accessing resources

key - String name of the boolean value to look up

defaultValue - value to be returned if the specified resource could be not be found.

Returns:

String value of the specified property, or an empty string if it could not be found.

logControlled

public static void logControlled(Context context,
                                 String msg)

Used internally to log only when the com.twitter.sdk.android.TRACE_ENABLED resource value is set to true. When it is, this API passes processing to the log API.

logControlledError

public static void logControlledError(Context context,
                                      String msg,
                                      Throwable tr)

Used internally to log errors only when the com.twitter.sdk.android.TRACE_ENABLED resource value is set to true. When it is, this API passes processing to the logError API.

logControlled

public static void logControlled(Context context,
                                 int level,
                                 String tag,
                                 String msg)

Used internally to log only when the com.twitter.sdk.android.TRACE_ENABLED resource value is set to true. When it is, this API passes processing to the log API.

logOrThrowIllegalStateException

public static void logOrThrowIllegalStateException(String logTag,
                                                   String errorMsg)

If Twitter.isDebug(), throws an IllegalStateException, else logs a warning.

Parameters:

logTag - the log tag to use for logging

errorMsg - the error message
