StrictMode.ThreadPolicy.Builder

extends Object
java.lang.Object
   ↳ android.os.StrictMode.ThreadPolicy.Builder

Class Overview

Creates StrictMode.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);
 

Summary

Public Constructors

Public Constructors

public StrictMode.ThreadPolicy.Builder ()

Added in API level 9

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 StrictMode.ThreadPolicy.Builder (StrictMode.ThreadPolicy policy)

Added in API level 9

Initialize a Builder from an existing ThreadPolicy.

Public Methods

public StrictMode.ThreadPolicy build ()

Added in API level 9

Construct the ThreadPolicy instance.

Note: if no penalties are enabled before calling build, penaltyLog() is implicitly set.

public StrictMode.ThreadPolicy.Builder detectAll ()

Added in API level 9

Detect everything that's potentially suspect.

As of the Gingerbread release this includes network and disk operations but will likely expand in future releases.

public StrictMode.ThreadPolicy.Builder detectCustomSlowCalls ()

Added in API level 11

Enable detection of slow calls.

public StrictMode.ThreadPolicy.Builder detectDiskReads ()

Added in API level 9

Enable detection of disk reads.

public StrictMode.ThreadPolicy.Builder detectDiskWrites ()

Added in API level 9

Enable detection of disk writes.

public StrictMode.ThreadPolicy.Builder detectNetwork ()

Added in API level 9

Enable detection of network operations.

public StrictMode.ThreadPolicy.Builder penaltyDeath ()

Added in API level 9

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.

public StrictMode.ThreadPolicy.Builder penaltyDeathOnNetwork ()

Added in API level 11

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.

public StrictMode.ThreadPolicy.Builder penaltyDialog ()

Added in API level 9

Show an annoying dialog to the developer on detected violations, rate-limited to be only a little annoying.

public StrictMode.ThreadPolicy.Builder penaltyDropBox ()

Added in API level 9

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.

public StrictMode.ThreadPolicy.Builder penaltyFlashScreen ()

Added in API level 11

Flash the screen during a violation.

public StrictMode.ThreadPolicy.Builder penaltyLog ()

Added in API level 9

Log detected violations to the system log.

public StrictMode.ThreadPolicy.Builder permitAll ()

Added in API level 9

Disable the detection of everything.

public StrictMode.ThreadPolicy.Builder permitCustomSlowCalls ()

Added in API level 11

Disable detection of slow calls.

public StrictMode.ThreadPolicy.Builder permitDiskReads ()

Added in API level 9

Disable detection of disk reads.

public StrictMode.ThreadPolicy.Builder permitDiskWrites ()

Added in API level 9

Disable detection of disk writes.

public StrictMode.ThreadPolicy.Builder permitNetwork ()

Added in API level 9

Disable detection of network operations.
