StrictMode.ThreadPolicy.Builder
extends Object
java.lang.Object | |
↳ | android.os.StrictMode.ThreadPolicy.Builder |
Creates ThreadPolicy
instances. Methods whose names start with detect
specify what problems we should look for. Methods whose names start with penalty
specify what we should do when we detect a problem.
You can call as many detect
and penalty
methods as you like. Currently
order is insignificant: all penalties apply to all detected problems.
For example, detect everything and log anything that's found:
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder() .detectAll() .penaltyLog() .build(); StrictMode.setThreadPolicy(policy);

Inherited methods | |
---|---|
public Builder ()
Create a Builder that detects nothing and has no violations. (but note that build()
will default to enabling penaltyLog()
if no other penalties are
specified)
public Builder (StrictMode.ThreadPolicy policy)
Initialize a Builder from an existing ThreadPolicy.
Parameters | |
---|---|
policy |
StrictMode.ThreadPolicy |
public StrictMode.ThreadPolicy build ()
Construct the ThreadPolicy instance.
Note: if no penalties are enabled before calling build
, penaltyLog()
is implicitly set.
Returns | |
---|---|
StrictMode.ThreadPolicy |
public StrictMode.ThreadPolicy.Builder detectAll ()
Detect everything that's potentially suspect.
As of the Gingerbread release this includes network and disk operations but will likely expand in future releases.
Returns | |
---|---|
StrictMode.ThreadPolicy.Builder |
This value cannot be null . |
public StrictMode.ThreadPolicy.Builder detectCustomSlowCalls ()
Enable detection of slow calls.
Returns | |
---|---|
StrictMode.ThreadPolicy.Builder |
This value cannot be null . |
public StrictMode.ThreadPolicy.Builder detectDiskReads ()
Enable detection of disk reads.
Returns | |
---|---|
StrictMode.ThreadPolicy.Builder |
This value cannot be null . |
public StrictMode.ThreadPolicy.Builder detectDiskWrites ()
Enable detection of disk writes.
Returns | |
---|---|
StrictMode.ThreadPolicy.Builder |
This value cannot be null . |
public StrictMode.ThreadPolicy.Builder detectNetwork ()
Enable detection of network operations.
Returns | |
---|---|
StrictMode.ThreadPolicy.Builder |
This value cannot be null . |
public StrictMode.ThreadPolicy.Builder detectResourceMismatches ()
Enables detection of mismatches between defined resource types and getter calls.
This helps detect accidental type mismatches and potentially expensive type conversions when obtaining typed resources.
For example, a strict mode violation would be thrown when calling TypedArray.getInt(int, int)
on an index that contains a
String-type resource. If the string value can be parsed as an integer, this method
call will return a value without crashing; however, the developer should format the
resource as an integer to avoid unnecessary type conversion.
Returns | |
---|---|
StrictMode.ThreadPolicy.Builder |
This value cannot be null . |
public StrictMode.ThreadPolicy.Builder detectUnbufferedIo ()
Detect unbuffered input/output operations.
Returns | |
---|---|
StrictMode.ThreadPolicy.Builder |
This value cannot be null . |
public StrictMode.ThreadPolicy.Builder penaltyDeath ()
Crash the whole process on violation. This penalty runs at the end of all enabled penalties so you'll still get see logging or other violations before the process dies.
Unlike penaltyDeathOnNetwork()
, this applies to disk reads, disk writes,
and network usage if their corresponding detect flags are set.
Returns | |
---|---|
StrictMode.ThreadPolicy.Builder |
This value cannot be null . |
public StrictMode.ThreadPolicy.Builder penaltyDeathOnNetwork ()
Crash the whole process on any network usage. Unlike penaltyDeath()
, this
penalty runs before anything else. You must still have called detectNetwork()
to enable this.
In the Honeycomb or later SDKs, this is on by default.
Returns | |
---|---|
StrictMode.ThreadPolicy.Builder |
This value cannot be null . |
public StrictMode.ThreadPolicy.Builder penaltyDialog ()
Show an annoying dialog to the developer on detected violations, rate-limited to be only a little annoying.
Returns | |
---|---|
StrictMode.ThreadPolicy.Builder |
This value cannot be null . |
public StrictMode.ThreadPolicy.Builder penaltyDropBox ()
Enable detected violations log a stacktrace and timing data to the DropBox
on policy violation. Intended mostly for platform
integrators doing beta user field data collection.
Returns | |
---|---|
StrictMode.ThreadPolicy.Builder |
This value cannot be null . |
public StrictMode.ThreadPolicy.Builder penaltyFlashScreen ()
Flash the screen during a violation.
Returns | |
---|---|
StrictMode.ThreadPolicy.Builder |
This value cannot be null . |
public StrictMode.ThreadPolicy.Builder penaltyListener (Executor executor, StrictMode.OnThreadViolationListener listener)
Call #OnThreadViolationListener#onThreadViolation(Violation)
on specified
executor every violation.
Parameters | |
---|---|
executor |
Executor : This value cannot be null . |
listener |
StrictMode.OnThreadViolationListener : This value cannot be null . |
Returns | |
---|---|
